{"cve":"CVE-2026-54097","nvd":{"published":"2026-06-25T19:16:41.753","modified":"2026-06-26T14:17:05.303","status":"Deferred","description":"File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.6, a low-privileged authenticated user of filebrowser (with create + delete permissions in their own isolated scope) can silently destroy share-link records belonging to any other user — including the administrator — by performing a legitimate DELETE on a file in their own directory whose logical path happens to be a byte-prefix of another user's stored share.Link.Path. The file contents of the victim are not exposed, but the victim's share links are irrevocably wiped. This vulnerability is fixed in 2.63.6.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.2},"cvss_v3":null,"cwes":["CWE-639"],"references":["https://github.com/filebrowser/filebrowser/commit/0231b7ebdfbe77a6c54027d30c4856c3fd81ee4d","https://github.com/filebrowser/filebrowser/releases/tag/v2.63.6","https://github.com/filebrowser/filebrowser/security/advisories/GHSA-5ww9-jg6q-38r7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-54097","score":0.0045,"percentile":0.39104,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5ww9-jg6q-38r7","url":"https://osv.dev/vulnerability/GHSA-5ww9-jg6q-38r7","summary":"File Browser: Cross-user unauthorized share-link deletion via unbounded prefix match in DeleteWithPathPrefix","modified":"2026-07-21T15:00:42.291010128Z","packages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser","purl":"pkg:golang/github.com/filebrowser/filebrowser","ranges":["<=1.11.0"],"fixed":[]},{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","ranges":["<2.63.6"],"fixed":["2.63.6"]}]},{"id":"GO-2026-5159","url":"https://osv.dev/vulnerability/GO-2026-5159","summary":"File Browser: Cross-user unauthorized share-link deletion via unbounded prefix match in DeleteWithPathPrefix in github.com/filebrowser/filebrowser","modified":"2026-06-25T18:45:28.035203544Z","packages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser","purl":"pkg:golang/github.com/filebrowser/filebrowser","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","ranges":["<2.63.6"],"fixed":["2.63.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
