Prior to 1.5.2-stable and 2.0.1-beta, file read handling in backend/pkg/indexing/indexingFiles.go resolves symbolic links through GetRealPath without confirming that the resolved target remains inside the source root and the user's authorized scope. Download, preview, media, OnlyOffice, and public-share read flows that enable FollowSymlinks can therefore serve an out-of-scope target through a reachable in-scope symlink. An authenticated user with download access can read server-accessible files outside the assigned scope, and a holder of a public share link can do the same without an account when the shared directory exposes such a symlink. This issue is fixed in 1.5.2-stable and 2.0.1-beta.","state":0,"publishedAt":"2026-10-27T17:48:04.364+00:00","modifiedAt":"2026-10-27T17:48:04.364+00:00","affected":[{"ecosystem":"Vendor product","name":"filebrowser","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"gtsteffaniak\",\n                    \"product\": \"filebrowser\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.5.2-stable\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0-beta, < 2.0.1-beta\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6,"severity":"HIGH"}],"references":["https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-mgqf-5mf5-prfj","https://github.com/gtsteffaniak/filebrowser/pull/2795","https://github.com/gtsteffaniak/filebrowser/pull/2800","https://github.com/gtsteffaniak/filebrowser/commit/3c8c02414eefd3351ffe437fa39ff6eb150ffa67","https://github.com/gtsteffaniak/filebrowser/commit/4126edeb07a015c3809a89249b283e07a4e50c38","https://github.com/gtsteffaniak/filebrowser/releases/tag/v1.5.2-stable","https://github.com/gtsteffaniak/filebrowser/releases/tag/v2.0.1-beta"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116682","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116682","identifiers":["CVE-2026-116682"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
