It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-91205 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2026-91205/ (Markdown: https://insights.sbomify.com/CVE-2026-91205/index.md)","id":"CVE-2026-91205","markdown":"https://insights.sbomify.com/CVE-2026-91205/index.md","name":"CVE-2026-91205","record":{"aliases":["DEBIAN-CVE-2026-91205","GHSA-5jj9-v4xp-h5h5","UBUNTU-CVE-2026-91205"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cockpit Files","requires_auth":"low_privilege","summary":"A local attacker can exploit a race condition in Cockpit Files to hijack file ownership via symlink attacks, leading to unauthorized data access or modification.","user_interaction":"required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-363","name":"Race Condition Enabling Link Following"}],"description":"A flaw was found in cockpit-files. A local unprivileged attacker can exploit a race condition during directory creation with owner assignment. By controlling a writable parent directory, the attacker can replace a newly created directory with a symbolic link (symlink) before the ownership change operation (chown) is applied. This allows the attacker to redirect the ownership change to an arbitrary file, potentially leading to information disclosure or unauthorized modification of sensitive files.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Cockpit-files: cockpit-files: local attacker can hijack file ownership via symlink race","id":"CVE-2026-91205","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Apache Roller: Reflected XSS in the optional LDAP comment authenticator","id":"CVE-2026-91206"},"packages":[],"prev":{"headline":"Apache Roller: Stored javascript: URI in HTML comments","id":"CVE-2026-91204"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 9"],"published":"2026-09-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Red Hat"]},"summary":"A local attacker can exploit a race condition in Cockpit Files to hijack file ownership via symlink attacks, leading to unauthorized data access or modification.","url":"https://insights.sbomify.com/CVE-2026-91205/"}
