Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-63125 exists.\n\nAffected product: lxc incus. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-63125/ (Markdown: https://insights.sbomify.com/CVE-2026-63125/index.md)","id":"CVE-2026-63125","markdown":"https://insights.sbomify.com/CVE-2026-63125/index.md","name":"CVE-2026-63125","record":{"aliases":["DEBIAN-CVE-2026-63125","GHSA-6rqx-22hc-qm36","UBUNTU-CVE-2026-63125"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Incus container manager","requires_auth":"low_privilege","summary":"An unprivileged user can execute arbitrary code as root by crafting an image with a symlinked backup.yaml file, affecting Incus administrators.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-61","name":"UNIX Symbolic Link (Symlink) Following"},{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Incus is a system container and virtual machine manager.
