| CVE-2026-103885 | 7.5 high | 0.00% | no CPE yet | Asymmetric Resource Consumption vulnerability in Apache Directory LDAP API. A LDAP server using the LDAP API (like Apache DS) may consume 100% of a CPU core indefinitely when processing some badly crafted Telephone Numbers. This issue affects Apache Directory LDAP API: from 2.1.0 before 2.1.9. Users are recommended to upgrade to version 2.1.9, which fixes the issue. | 8 Oct |
| CVE-2026-91494 | 7.4 high | 0.00% | oracle, identity_manager_connector | Vulnerability in the Oracle Identity Manager Connector product of Oracle Fusion Middleware (component: LDAP Gateway). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Identity Manager Connector. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Identity Manager Connector accessible data as well as unauthorized access to critical data or complete access to all Oracle Identity Manager Connector accessible data. CVSS 3.1 Base Score 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N). | Tue 27 Oct |
| CVE-2026-33376 | 7.4 high | 0.00% | grafana | When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses. Addresses specifying a mask explicitly are not affected; to mitigate easily, add the desired mask (usually /128) to the addresses. Only auth proxy is affected; Okta, SAML, LDAP, etc are unaffected here. | Mon 26 Oct |
| CVE-2026-90979 | 7.3 high | 0.00% | apache, karaf | LDAPCache and LDAPBackingEngine build LDAP search filters for user lookup and role lookup by textually substituting the placeholders %u, %dn, and %fqdn (drawn from the login name, the resolved user DN, and its fully qualified namespace form) into administrator-configured filter templates (userFilter, roleFilter). Before the fix, the only sanitization applied to the substituted value was double backslashed: filter = filter.replaceAll(Pattern.quote("%u"), Matcher.quoteReplacement(user)); filter = filter.replace("\\", "\\\\"); This does not escape the other characters RFC 4515 requires escaping in an LDAP search filter: *, (, ), and NUL. A login name containing any of these can change the structure of the resulting filter rather than being matched as a literal value (e.g. a crafted username can turn an equality match into a wildcard match, or close/reopen filter clauses), widening what the search returns and potentially causing a login or role lookup to match an LDAP entry other than the intended one, over-granting roles, and depending on deployment-specific filter templates, potentially affecting which account a login resolved to. It's not exploitable through every entry points: LDAPLoginModule and LDAPPubkeyLoginModule both called Util.doRFC2254Encoding() (correct RFC 4515 escaping) on the login name before handing it to LDAPCache, which masked the missing escaping in LDAPCache for those two call paths. Using LDAPCache directly (bypassing the login modules) does not reproduce through the normal LDAPLoginModule/LDAPPubkeyLoginModule authentication flow for this reason. It does reproduce through two other call paths that reach LDAPCache/LDAPBackingEngine without any prior escaping: * GSSAPILdapLoginModule passes the NameCallback name straight through, unescaped. * LDAPBackingEngine (listRoles) passes principal.getName() straight through, unescaped. | 8 Oct |
| CVE-2026-60418 | 7.2 high | 0.00% | oracle, unified_directory | Vulnerability in the Oracle Unified Directory product of Oracle Fusion Middleware (component: OUD Core).

CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N). | Tue 27 Oct |
| CVE-2025-62795 | 7.1 high | 0.00% | fit2cloud, jumpserver | JumpServer is an open source bastion host and an operation and maintenance security audit system. Prior to v3.10.21-lts and v4.10.12-lts, a low-privileged authenticated user can invoke LDAP configuration tests and start LDAP synchronization by sending crafted messages to the /ws/ldap/ WebSocket endpoint, bypassing authorization checks and potentially exposing LDAP credentials or causing unintended sync operations. This vulnerability is fixed in v3.10.21-lts and v4.10.12-lts. | 19 Oct |
| CVE-2025-48343 | 7.1 high | 0.00% | no CPE yet | Cross-Site Request Forgery (CSRF) vulnerability in Aaron Axelsen WPMU Ldap Authentication wpmuldap allows Stored XSS.This issue affects WPMU Ldap Authentication: from n/a through <= 5.0.1. | 18 Oct |
| CVE-2026-78553 | 7.0 high | 0.00% | no CPE yet | RansomLook created its Flask session-signing key without explicitly restricting the file permissions. The secret_key file was created using the process's default permissions and umask, resulting in permissions such as 0644 under a common 022 umask. Consequently, other local users able to access the RansomLook home directory could read the application's cryptographic secret. The exposed key is security-critical because it is used to sign Flask session cookies and is also involved in the legacy API-key key derivation. An attacker who obtains the key can generate valid session cookies and impersonate an authenticated user, including an administrator. In LDAP configurations, exploitation may be particularly straightforward because the session user loader does not require the supplied username to correspond to an existing local user. Successful exploitation requires local access sufficient to read the improperly protected file, but can result in complete compromise of RansomLook's authentication and authorization controls. The patch creates new secret-key files atomically with permissions 0600 and also restricts permissions on existing key files during application startup. | 12 Oct |
| CVE-2026-7820 | 6.9 medium | 0.00% | pgadmin, pgadmin_4 | Improper restriction of excessive authentication attempts (CWE-307) in pgAdmin 4. pgAdmin enforces MAX_LOGIN_ATTEMPTS only inside its custom /authenticate/login view. Flask-Security's default /login view, which is registered automatically by security.init_app() and is reachable on every server, never consulted the User.locked field: pgAdmin's User model relied on Flask-Security's UserMixin.is_locked() (which always returns 'not locked') and Flask-Login's is_active (which only checks the active column, not locked). An attacker who triggered an account lockout via /authenticate/login could therefore obtain a session by re-submitting valid credentials directly to /login, defeating the brute-force-protection control for accounts using the INTERNAL authentication source. The same bypass also means that login attempts via /login are never rate-limited, so an attacker can perform an unbounded online password-guessing attack against INTERNAL accounts regardless of MAX_LOGIN_ATTEMPTS. Fix overrides User.is_active and User.is_locked() so the locked column is enforced on every authentication path. LDAP, OAuth2, Kerberos, and Webserver users are not reachable by this bypass because they have no local password and are rejected by Flask-Security's LoginForm.validate before the locked check; the lockout itself is also internal-only (the /authenticate/login view filters by auth_source=INTERNAL). This issue affects pgAdmin 4: before 9.15. | Mon 26 Oct |
| CVE-2026-113438 | 6.9 medium | 0.00% | no CPE yet | Pleasanter provided fails to properly verify passwords in LDAP authentication when processing specially crafted requests under certain configurations. If exploited, an attacker may bypass LDAP authentication by providing only a valid Login ID, without a password. As a result, an attacker may view, alter or delete information stored in the product with the privilege of the account used to log in. | Mon 26 Oct |
| CVE-2026-49129 | 6.9 medium | 0.00% | no CPE yet | Music Player Daemon (MPD) before version 0.24.11 contains a server-side request forgery vulnerability in CurlInputPlugin where CURLOPT_FOLLOWLOCATION is set without CURLOPT_REDIR_PROTOCOLS_STR, allowing unauthenticated attackers to bypass the http/https scheme restriction by causing a malicious HTTP server to redirect to non-HTTP protocols such as gopher, ftp, sftp, ldap, dict, rtmp, or rtsp. Attackers can trigger this vulnerability via MPD commands that initiate URL fetches, including add, readcomments, albumart, readpicture, or load, to interact with internal or restricted network services on systems running libcurl versions prior to 7.85.0. | Mon 26 Oct |
| CVE-2026-11748 | 6.9 medium | 0.00% | no CPE yet | A vulnerability has been identified in centraldogma-server-auth-shiro versions prior to 0.84.0, where the SearchFirstActiveDirectoryRealm substitutes the login username into an LDAP search filter without neutralizing LDAP filter metacharacters, allowing an unauthenticated attacker to manipulate the filter to cause authentication confusion and enumerate the directory structure. | Sun 25 Oct |
| CVE-2026-59652 | 6.9 medium | 0.00% | bouncycastle, bc-java | In Bouncy Castle for Java before 1.85, LDAP filter injection in legacy jdk1.4 LDAPStoreHelper. | Fri 23 Oct |

| CVE-2026-67223 | 6.3 medium | 0.00% | broadcom, rabbitmq_server | RabbitMQ is a messaging and streaming broker. The advisory establishes affected 3.13, 4.0, 4.1, 4.2, and 4.3 maintenance lines but contains conflicting first-fixed versions for the 3.13, 4.0, and 4.1 lines. fill/2 substitutes ${username} into user_dn_pattern without RFC 4514 DN escaping, allowing a crafted username to alter the LDAP bind DN and potentially select a different directory entry. Exploitation requires rabbitmq_auth_backend_ldap with a user_dn_pattern containing ${username}, a directory layout in which the injected suffix resolves usefully, and a password valid for the resulting DN. The advisory body identifies 3.13.15, 4.0.20, 4.1.11, 4.2.9, and 4.3.3 as fixed, while structured metadata identifies 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3. No fixed-version assertion is certifiable until a curator resolves this conflict. | 15 Oct |
| CVE-2025-59149 | 6.2 medium | 0.00% | oisf, suricata | Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community.

| CVE-2026-10759 | 5.5 medium | 0.00% | no CPE yet | A flaw in Portal for ArcGIS could allow LDAP injection through administrative functionality that constructs Active Directory or LDAP search queries without sufficient input neutralization. An authenticated administrator could supply crafted input that modifies the intended LDAP query and causes unintended directory operations. | Mon 26 Oct |
| CVE-2025-61911 | 5.5 medium | 0.00% | python-ldap | python-ldap is a lightweight directory access protocol (LDAP) client API for Python. In versions prior to 3.4.5, the sanitization method `ldap.filter.escape_filter_chars` can be tricked to skip escaping of special characters when a crafted `list` or `dict` is supplied as the `assertion_value` parameter, and the non-default `escape_mode=1` is configured. The method `ldap.filter.escape_filter_chars` supports 3 different escaping modes. `escape_mode=0` (default) and `escape_mode=2` happen to raise exceptions when a `list` or `dict` object is supplied as the `assertion_value` parameter. However, `escape_mode=1` computes without performing adequate logic to ensure a fully escaped return value. If an application relies on the vulnerable method in the `python-ldap` library to escape untrusted user input, an attacker might be able to abuse the vulnerability to launch ldap injection attacks which could potentially disclose or manipulate ldap data meant to be inaccessible to them. Version 3.4.5 fixes the issue by adding a type check at the start of the `ldap.filter.escape_filter_chars` method to raise an exception when the supplied `assertion_value` parameter is not of type `str`. | 19 Oct |
| CVE-2025-61912 | 5.5 medium | 0.00% | python-ldap | python-ldap is a lightweight directory access protocol (LDAP) client API for Python. In versions prior to 3.4.5, ldap.dn.escape_dn_chars() escapes \x00 incorrectly by emitting a backslash followed by a literal NUL byte instead of the RFC-4514 hex form \00. Any application that uses this helper to construct DNs from untrusted input can be made to consistently fail before a request is sent to the LDAP server (e.g., AD), resulting in a client-side denial of service. Version 3.4.5 contains a patch for the issue. | 19 Oct |
| CVE-2025-13467 | 5.5 medium | 0.00% | no CPE yet | A flaw was found in the Keycloak LDAP User Federation provider. This vulnerability allows an authenticated realm administrator to trigger deserialization of untrusted Java objects via a malicious LDAP server configuration. | 18 Oct |
| CVE-2026-78359 | 5.4 medium | 0.00% | no CPE yet | OTRS does not sufficiently enforce the uniqueness of customer user identities across multiple configured CustomerUser backends. When multiple backends, such as a database and LDAP, are configured, the uniqueness check for customer user email addresses is performed only within the selected backend. As a result, an authenticated user with permission to create or modify customer users may create a customer user whose email address is already assigned to a customer user in another backend. This can result in multiple customer user records representing the same communication identity. Depending on the affected workflow and backend resolution, customer-related information or email communication may subsequently be associated with or exposed to the wrong customer user. The vulnerability does not allow unauthenticated users to create customer accounts. Exploitation requires permissions to create or modify customer users. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X Please note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected | 15 Oct |
| CVE-2026-118426 | 5.3 medium | 0.00% | octopus deploy, octopus server | In affected versions of Octopus Server with the LDAP authentication provider enabled, any authenticated user could call the LDAP user search and LDAP group search. | Thu 29 Oct |
| CVE-2026-45009 | 5.3 medium | 0.00% | no CPE yet | phpMyFAQ before 4.1.2 contains an insufficient authorization vulnerability in admin-api routes that allows authenticated ordinary users to access administrative endpoints by only checking login status instead of verifying backend privileges. Attackers with valid frontend user accounts can access sensitive backend operational information including dashboard versions, LDAP configuration, Elasticsearch statistics, and health-check data. | Mon 26 Oct |
| CVE-2026-27860 | 5.3 medium | 0.00% | dovecot, open-xchange | If auth_username_chars is empty, it is possible to inject arbitrary LDAP filter to Dovecot's LDAP authentication.

No publicly available exploits are known. | Mon 26 Oct |
| CVE-2026-57962 | 5.3 medium | 0.00% | mozilla, thunderbird | A malicious LDAP server, which a Thunderbird user is configured to query for address-book autocomplete, can stash arbitrarily large amounts of attacker-supplied data into the Thunderbird LDAP client until it crashes due to memory exhaustion. This vulnerability was fixed in Thunderbird 152.0.1 and Thunderbird 140.12.1. | Sun 25 Oct |
| CVE-2026-55106 | 5.3 medium | 0.00% | no CPE yet | authentik is an open-source identity provider. Prior to 2026.2.6 and 2026.5.5, a diagnostic action on the LDAP Source API does not enforce the object-level read-authorization filter used by the rest of the API. Any party able to reach the API, including an unauthenticated client, can invoke the diagnostic action against a configured LDAP Source. The server then connects to the upstream directory using the source's configured bind credentials and returns a bounded set of directory entries. The response exposes the distinguished names of those entries and the names of the attributes present on them, revealing directory structure, naming conventions, and the existence of specific accounts and groups, but not attribute values. Deployments without a configured LDAP Source are not affected. This issue is fixed in versions 2026.2.6 and 2026.5.5. | 22 Oct |
| CVE-2026-93635 | 5.3 medium | 0.00% | no CPE yet | LDAP filter injection in Zimbra Collaboration Suite 10.1.0 through 10.1.21 allows unauthenticated attackers to alter external LDAP search filters. On domains using search-filter authentication and lazy provisioning, this creates a password oracle for external directory users. Authenticated S/MIME lookups can also return certificates and identity data for unintended directory entries. | 16 Oct |

| CVE-2026-63168 | 5.1 medium | 0.00% | no CPE yet | Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to persist unneutralized markup by submitting malicious values as two-dimensional POST arrays through the LDAP/person import flow, bypassing the paramsFilter() request parameter filter which failed to recurse into nested arrays. Attackers can inject arbitrary script code into a user profile that is later rendered to other users, resulting in execution of malicious scripts in victims' browsers. | 18 Oct |
| CVE-2026-9801 | 4.9 medium | 0.00% | redhat, build_of_keycloak | A flaw was found in Keycloak. A remote attacker with high privileges, such as a realm administrator configuring a malicious Lightweight Directory Access Protocol (LDAP) server or an attacker compromising an upstream LDAP server, could exploit this vulnerability. By sending a malformed LDAP password policy response during a password authentication request, the attacker can trigger an OutOfMemoryError. This causes the Keycloak Java Virtual Machine (JVM) to terminate, leading to a denial of service (DoS) for all realms on the affected node. | Mon 26 Oct |
