VU#701544: mpc-lib hardened derivation fails to protect ancestor isolation
Overview Fireblocks' mpc-lib library contains a cryptographic fail-open vulnerability in its BIP32 hardened derivation implementation in the case of a missing private parent key. This breaks the ancestor isolation property of hardened derivation, allowing an attacker with a compromised lower-level signer share to recover the higher-level share it was derived from. Description Fireblocks is a digital-asset custody and wallet platform that secures the private keys behind cryptocurrency wallets for institutions and exchanges, using multi-party computation (MPC) so that no single machine ever hol…

VU#128947: COVESA vsomeip excessive memory allocation in reliable (TCP) endpoint buffer handling
Overview vsomeip, COVESA's open source implementation of the SOME/IP automotive communication middleware, contained a memory allocation vulnerability present in versions 3.7.3 and below. A vsomeip reliable (TCP) SOME/IP endpoint grows its receive buffer to an attacker-declared message size before validating that the declared bytes have actually been received, allowing a remote, unauthenticated peer to exhaust host memory and deny service. The issue was reported publicly as COVESA/vsomeip issue #1009 and fixed in release 3.7.4 (2026-07-06). Description CVE-2026-91141 vsomeip is a middleware im…

VU#645818: Xerj Console API authentication bypass leads to unauthorized credential minting
Overview An authentication bypass vulnerability in the Xerj Console API allows sessions to bypass passkey-backed requirements during token issuance. By exploiting this flaw, an attacker with an existing valid token can create independent, persistent successor credentials directly through the console API. This allows the attacker to maintain access and potentially escalate privileges within the Xerj ecosystem, even if the initial token is revoked. Description Xerj is an open-source search and indexing engine tailored specifically for AI agents utilizing the Elasticsearch API, allowing AI model…

VU#410595: Google BoringSSL Name Constraints bypass in SAN validation logic
Overview Five Name Constraints findings in BoringSSL (VU#410595.8–.12) describe cases where certificate names may not be constrained as intended. Records .8, .9, .10 and .12 concern the legacy crypto/x509 path; .11 concerns the newer pki path. Two have been fixed, one is accepted, one is disputed, and one was declined. Description Name Constraints limit the names a subordinate certificate authority may issue. The reports concern how BoringSSL applies those limits to certain SAN (Subject Alternative Name) forms. The records do not share one status, and they do not all affect the same validatio…

VU#948176: Multiple TLS libraries can bypass delegation enforcement
Overview This note covers thirteen library-specific records (VU#948176.6, .8–.19) of how widely used TLS libraries apply X.509 Name Constraints. The records describe cases where a constrained name may be accepted by one library and rejected by another. Some are fixed, some remain under review, and some were not accepted as security issues. Description Name Constraints are meant to keep a subordinate CA inside an allowed namespace. The records cover several name forms and do not all have the same classification. VU#948176.7 does not exist. DNS case-sensitivity and wildcards. While RFC 5280 req…

VU#166125: Bisheng has authentication bypass vulnerabilities
Overview Bisheng contains three vulnerabilities: a pre-authentication account takeover mechanism via a legacy single sign-on (SSO) endpoint; an Insecure Direct Object Reference (IDOR) vulnerability that exposes cross-user workflow data; and prior to version 2.5.0, authenticated attackers could perform cross-user LLM credential abuse and data disclosure due to missing service-layer access checks. Together, these flaws could allow unauthenticated attackers to gain administrative control while enabling authenticated users access to sensitive data and hardcoded credentials. Description Bisheng is…

VU#456950: Komodo Periphery agent contains an OS command injection vulnerability
Overview Versions <= 2.2.0 of Periphery, an agent within the Komodo server management platform, is vulnerable to OS command injection due to missing validation of container names, through two vectors: container destruction and container log searches. This allows an authenticated attacker to execute arbitrary commands as root on the underlying host, enabling persistent compromise of infrastructure. Description Komodo is an open-source server and deployment manager, maintained by mogh.tech, widely used in self-hosted and Docker multi-server environments. Periphery is an agent service installed…

VU#382143: Lowcoder Query Library API contains cross-tenant authorization bypass allowing for data exfiltration
Overview Lowcoder, version 2.4.10, contains an authorization bypass vulnerability in its Query Library feature’s API. Authenticated users with an admin or dev role can access private library-query data from other organizations within a multi-tenant Lowcoder instance. Description CVE-2026-16753 Lowcoder is an open-source low-code platform that allows individuals with minimal coding experience to build web applications through a visual drag-and-drop interface. Each Lowcoder project contains a centralized Query Library which stores the workspace’s data queries and sources for quick reuse; howeve…

VU#573195: Go, OpenSSL, Apple, LibreSSL, pyca, wolfSSL Name-Constraint inconsistency in RFC 5280 implementation
Overview This note covers differences in how TLS libraries interpret X.509 Name Constraints. A certificate that one library accepts may be rejected by another. Some of those differences are defects; others follow from behavior that RFC 5280 does not fully specify. Description The observed differences concern DNS name comparison, IP address handling, URI-authority parsing, and wildcard matching. These include both implementation defects and behavior not fully specified by RFC 5280. DNS-name comparison. RFC 5280 requires case-insensitive matching for DNS names. GnuTLS compared some names' case-…

VU#553437: InsydeH2O IHISI SMM is vulnerable to unsafe memory write operations
Overview An Out-of-bounds Write vulnerability in the InsydeH2O IHISI software used by HP PC BIOS can allow a local attacker with OS kernel privileges to perform arbitrary physical memory writes, including writes to System Management RAM (SMRAM). Because the vulnerable code executes in System Management Mode (SMM), successful exploitation can allow an attacker to modify SMM-protected memory and potentially achieve arbitrary code execution in SMM. Depending on the platform's memory and firmware configuration, the arbitrary physical memory write primitive may also have implications for UEFI firm…

VU#762428: Authlib library contains a signature‑verification bypass vulnerability
Overview Authlib (versions up to and including 1.7.2) contain a signature‑verification bypass in the JSON Web Signature (JWS) general JSON serialization handling. The JsonWebSignature.deserialize_json() function accepts a JWS object with an empty "signatures" array and treats the payload as successfully verified, allowing attackers to supply arbitrary forged content without possessing any key material. Description Authlib is a Python library that provides tools for implementing OAuth, OpenID Connect, JWT/JWS/JWE (JSON Web Token / JSON Web Signature / JSON Web Encryption), and other modern aut…

VU#273940: Enterprise Access Management EAM does not rotate RSA keys
Overview Imprivata Enterprise Access Management (EAM), an authentication and single sign-on platform for enterprise and clinical environments, contains a vulnerability in versions 26.2.6 and below. The product provides no supported mechanism to rotate its RSA key pair after deployment, meaning the same key pair is used indefinitely to generate the appliance's X.509 certificate. Description CVE-2026-82356 Imprivata EAM uses an RSA key pair to generate the X.509 certificate that identifies the appliance to the clinical workstations, Electronic Health Record (EHR) platforms, and shared-device wo…
