| CVE | CVSS | EPSS | Vendor, product | Description | Modified |
|---|---|---|---|---|---|
| CVE-2026-62420 | 9.9 critical | 1.0% | canonical, lxd | An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass target project security restrictions during cross-project instance migrations. When moving an instance cross-project to a different cluster member via POST /1.0/instances/{name} with migration: true, project: <target>, and target: <member>, the destination node skips all project restriction checks because the request arrives as an internal cluster notification. An attacker can exploit this to introduce disallowed instance configurations into a restricted project. | Sat 24 Oct |
| CVE-2026-63293 | 9.9 critical | 1.0% | canonical, lxd | A link following vulnerability in LXD allows an attacker to achieve arbitrary file read and write operations on the host system. When importing or unpacking an image archive, LXD fails to validate whether the metadata.yaml file is a symbolic link. An attacker can exploit this flaw by providing a crafted image archive with a symlinked metadata.yaml file pointing to target file paths on the host system. | Sat 24 Oct |
| CVE-2026-63294 | 9.9 critical | 1.0% | canonical, lxd | A link following vulnerability in LXD allows an attacker to achieve root command execution on the host system. During the import or unpacking of crafted image or backup archives, LXD fails to properly validate and confine the backup.yaml file when it exists as a symbolic link. An attacker can exploit this flaw by providing a malicious archive with a symlinked backup.yaml file, causing LXD to process unconfined configuration metadata and execute arbitrary commands with root privileges. | Sat 24 Oct |
| CVE-2026-63298 | 9.9 critical | 1.0% | canonical, lxd | An improper neutralization of special elements vulnerability in LXD's NVIDIA instance configuration handling allows an authenticated attacker to inject arbitrary configuration directives. By supplying newline characters within the 'nvidia.driver.capabilities' or 'nvidia.require.*' configuration values, an attacker can manipulate the generated lxc.conf file. This flaw enables the attacker to execute arbitrary code on the host system with the privileges of the LXD daemon. | Sat 24 Oct |
| CVE-2026-63299 | 9.9 critical | 1.0% | canonical, lxd | An authorization bypass vulnerability in LXD allows an authenticated user to bypass project-level disk and volume limits. Two related code paths fail to verify resource limits during volume operations: the storagePoolVolumeTypePostMove function omits the limits.AllowVolumeCreation check before moving a volume across projects, and volume snapshot restore operations skip the AllowVolumeUpdate check when the configuration is nil (Config == nil). An attacker can exploit these flaws to allocate storage resources that exceed the administrative limits configured for a project. | Sat 24 Oct |
| CVE-2026-63300 | 9.9 critical | 1.0% | canonical, lxd | An improper validation vulnerability in the instancePostMigration function in lxd/instance_post.go of LXD allows an authenticated attacker with can_create_instances permissions on a restricted project to bypass project-level security restrictions. When migrating an instance between projects, LXD fails to validate the instance's configuration against the target project's enforced restrictions (such as restricted.containers.lowlevel, restricted.devices.*, and restricted.networks.access). An attacker can exploit this by creating a disallowed or high-privilege instance in an unrestricted project and subsequently moving it into the restricted project. | Sat 24 Oct |
| CVE-2026-66898 | 9.9 critical | 1.0% | canonical, lxd | A path traversal vulnerability in LXD allows an attacker to manipulate file system paths during backup import and restore operations. When importing or restoring a backup archive, LXD fails to validate instance and storage volume names contained within the archive metadata. An attacker can exploit this flaw by supplying a crafted backup archive with malicious instance or volume names containing path traversal sequences, potentially allowing file access or overwriting outside the designated restore directory. | Sat 24 Oct |
| CVE-2026-66897 | 9.9 critical | 1.0% | canonical, lxd | A path traversal vulnerability in LXD's instance template processing allows an attacker with container edit permissions, or any user launching a crafted image, to overwrite arbitrary files on the host system as root. When processing target template paths specified in metadata.yaml, LXD validates the path against a confined os.Root directory handle but subsequently opens and creates the file using os.Create with an unconfined string path. This discrepancy between path resolution checks and file creation allows an attacker to escape directory confinement, overwrite root-owned host files, and achieve host root code execution. | Sat 24 Oct |
| CVE-2026-9640 | 7.2 high | 1.0% | canonical, lxd | A privilege escalation vulnerability exists in LXD from 6.0 before 6.9, 5.21.0 before 5.21.5, and 5.0.0 before 5.0.7 regarding the handling of project-restriction policies during snapshot restoration.. An authenticated project operator in a restricted multi-tenant environment can bypass policy restrictions by importing a maliciously crafted instance backup containing restricted configuration keys within a snapshot. When the snapshot is restored, these restricted keys are applied to the live instance without policy validation. Starting the modified instance grants the operator unauthorized host root access. | Sun 25 Oct |
| CVE-2025-54293 | 7.1 high | 1.0% | canonical, lxd | Path Traversal in the log file retrieval function in Canonical LXD 5.0 LTS on Linux allows authenticated remote attackers to read arbitrary files on the host system via crafted log file names or symbolic links. | 12 Oct |
| CVE-2026-9639 | 6.5 medium | 1.0% | canonical, lxd | Nil-pointer dereference in CreateCustomVolumeFromBackup in LXD up to version 6.8 and 5.21 on Linux allows an authenticated user with can_create_storage_volumes permissions to cause a denial of service via a specially crafted custom-volume backup tarball that omits the expires_at snapshot field. | Sun 25 Oct |
| CVE-2026-63296 | 9.9 critical | 0.00% | canonical, lxd | An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass target project restrictions during instance migration. When migrating an instance to a target project, LXD accepts configuration overrides without validating the new configuration against the target project's enforced restrictions. An attacker can exploit this flaw to move instances with disallowed high-privilege configurations into restricted projects, bypassing security controls. | Sat 24 Oct |
| CVE-2026-63297 | 9.9 critical | 0.00% | canonical, lxd | An authorization bypass vulnerability in LXD due to a timing flaw during configuration merging allows an authenticated attacker to bypass target project restrictions during cross-project instance copies. When copying an instance to a target project, LXD performs restriction checks before configuration merging is complete, creating a time-of-check to time-of-use (TOCTOU) condition. An attacker can exploit this flaw to copy instances with disallowed high-privilege configurations into restricted projects, bypassing security controls. | Sat 24 Oct |
| CVE-2026-12411 | 9.6 critical | 0.00% | canonical, lxd | Broken Access Control in the devLXDInstancePatchHandler component of Canonical LXD allows an untrusted guest to mount, read, and overwrite another guest's custom storage volume via a crafted device PATCH request over /dev/lxd when security.devlxd.management.volumes is enabled. | Sun 25 Oct |
| CVE-2026-34177 | 9.1 critical | 0.00% | canonical, lxd | Canonical LXD versions 4.12 through 6.7 contain an incomplete denylist in isVMLowLevelOptionForbidden (lxd/project/limits/permissions.go), which omits raw.apparmor and raw.qemu.conf from the set of keys blocked under the restricted.virtual-machines.lowlevel=block project restriction. A remote attacker with can_edit permission on a VM instance in a restricted project can inject an AppArmor rule and a QEMU chardev configuration that bridges the LXD Unix socket into the guest VM, enabling privilege escalation to LXD cluster administrator and subsequently to host root. | Mon 26 Oct |
| CVE-2026-34178 | 9.1 critical | 0.00% | canonical, lxd | In Canonical LXD before 6.8, the backup import path validates project restrictions against backup/index.yaml in the supplied tar archive but creates the instance from backup/container/backup.yaml, a separate file in the same archive that is never checked against project restrictions. An authenticated remote attacker with instance-creation permission in a restricted project can craft a backup archive where backup.yaml carries restricted settings such as security.privileged=true or raw.lxc directives, bypassing all project restriction enforcement and allowing full host compromise. | Mon 26 Oct |
| CVE-2026-34179 | 9.1 critical | 0.00% | canonical, lxd | In Canonical LXD versions 4.12 through 6.7, the doCertificateUpdate function in lxd/certificates.go does not validate the Type field when handling PUT/PATCH requests to /1.0/certificates/{fingerprint} for restricted TLS certificate users, allowing a remote authenticated attacker to escalate privileges to cluster admin. | Mon 26 Oct |
| CVE-2026-16033 | 8.5 high | 0.00% | canonical, lxd | A path traversal vulnerability in LXD allows an attacker to achieve arbitrary host file read or unconstrained file creation. When processing image metadata templates, LXD fails to properly sanitize or restrict template file paths from escaping the instance templates directory (specifically affecting virtual machine / QEMU driver execution paths). An attacker can exploit this flaw by providing a crafted image archive with malicious template directives containing path traversal sequences, causing LXD to access or write files outside the intended template directory on the host system. | Fri 23 Oct |
| CVE-2025-54286 | 7.5 high | 0.00% | canonical, lxd | Cross-Site Request Forgery (CSRF) in LXD-UI in Canonical LXD versions >= 5.0 on Linux allows an attacker to create and start container instances without user consent via crafted HTML form submissions exploiting client certificate authentication. | 12 Oct |
| CVE-2025-54289 | 7.4 high | 0.00% | canonical, lxd | Privilege Escalation in operations API in Canonical LXD <6.5 on multiple platforms allows attacker with read permissions to hijack terminal or console sessions and execute arbitrary commands via WebSocket connection hijacking format | Fri 23 Oct |
| CVE-2025-54287 | 7.1 high | 0.00% | canonical, lxd | Template Injection in instance snapshot creation component in Canonical LXD (>= 4.0) allows an attacker with instance configuration permissions to read arbitrary files on the host system via specially crafted snapshot pattern templates using the Pongo2 template engine. | 12 Oct |
| CVE-2025-54290 | 6.9 medium | 0.00% | canonical, lxd | Information disclosure in image export API in Canonical LXD before 6.5 and 5.21.4 on Linux allows network attackers to determine project existence without authentication via crafted requests using wildcard fingerprints. | 12 Oct |
| CVE-2025-54291 | 6.9 medium | 0.00% | canonical, lxd | Information disclosure in images API in Canonical LXD before 6.5 and 5.21.4 on all platforms allows unauthenticated remote attackers to determine project existence via differing HTTP status code responses. | 12 Oct |
| CVE-2025-54288 | 5.1 medium | 0.00% | canonical, lxd | Information Spoofing in devLXD Server in Canonical LXD versions 4.0 and above on Linux container platforms allows attackers with root privileges within any container to impersonate other containers and obtain their metadata, configuration, and device information via spoofed process names in the command line. | 12 Oct |
| CVE-2026-28385 | 5.0 medium | 0.00% | canonical, lxd | In Canonical LXD versions 4.12 through 6.9, a Server-Side Request Forgery (SSRF) vulnerability in the image import functionality allows authenticated users with the can_create_images entitlement to interact with internal network infrastructure via the /images endpoint. When importing an image from a URL source, the LXD daemon fails to validate or restrict outbound destination IP addresses, allowing connections to loopback, RFC1918 private ranges, and cloud metadata endpoints. This enables error-based port scanning and unauthorized interaction with internal HTTP services from the daemon's network position. | Sun 25 Oct |
| CVE-2025-54292 | 4.8 medium | 0.00% | canonical, lxd | Path traversal in Canonical LXD LXD-UI versions before 6.5 and 5.21.4 on all platforms allows remote authenticated attackers to access or modify unintended resources via crafted resource names embedded in URL paths. | 12 Oct |
| CVE-2026-63295 | 4.3 medium | 0.00% | canonical, lxd | An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass project-level container isolation restrictions. When a project is configured with restrictions on container privileges (such as enforcing restricted.containers.privilege=isolated), LXD fails to enforce the requirement if an instance configuration omits the security.idmap.isolated key. An attacker can exploit this flaw by creating or updating an instance without explicitly setting security.idmap.isolated, bypassing the target project's security constraints. | Sat 24 Oct |
