An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-126499 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\n\nAffected product: jellyfin. 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-2026-126499/ (Markdown: https://insights.sbomify.com/CVE-2026-126499/index.md)","id":"CVE-2026-126499","markdown":"https://insights.sbomify.com/CVE-2026-126499/index.md","name":"CVE-2026-126499","record":{"aliases":["GHSA-6828-c7cx-hvqm","GHSA-v76m-gqgv-m4g2"],"analysis":{"component_type":"server_software","exploitable_when_present":false,"fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"media server","requires_auth":"none","requires_specific_call":false,"summary":"Unauthenticated attackers can delete or move directories on Jellyfin servers via crafted library names, including recursively wiping data and the database.","user_interaction":"not_required","vuln_class":"path_traversal","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Jellyfin before 12.0 contains a path traversal vulnerability in the DELETE /Library/VirtualFolders and POST /Library/VirtualFolders/Name endpoints that allows attackers to delete or move directories via unvalidated library names.
