It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54369 in the wild and no public exploit code.\n\nAffected product: acl. 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-2026-54369/ (Markdown: https://insights.sbomify.com/CVE-2026-54369/index.md)","id":"CVE-2026-54369","markdown":"https://insights.sbomify.com/CVE-2026-54369/index.md","name":"CVE-2026-54369","record":{"aliases":["AZL-91397","DEBIAN-CVE-2026-54369","ECHO-b5ce-94bd-9b5b","GHSA-53ch-pxc8-6g72","RHSA-2026:64805","RHSA-2026:67140","RHSA-2026:67142","RHSA-2026:67144","RHSA-2026:71656","RHSA-2026:72819","RHSA-2026:72820","ROOT-OS-DEBIAN-11-CVE-2026-54369","ROOT-OS-DEBIAN-12-CVE-2026-54369","ROOT-OS-DEBIAN-13-CVE-2026-54369","UBUNTU-CVE-2026-54369"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux ACL library","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges by exploiting symlink traversal in libacl functions to manipulate access control lists on arbitrary files.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"acl before version 2.4.0 contains a symlink traversal vulnerability in the libacl pathname-based functions acl_get_file(), acl_set_file(), acl_extended_file(), and acl_delete_def_file() that allows local attackers to escalate privileges by replacing any pathname component with a symbolic link.
