GHSA-7cj6-cw3p-4jpw
filebrowser versions before 2.63.17 contain a vulnerability in the DeleteWithPathPrefix function where paths are not normalized before querying the share index. This allows authenticated users to leave stale public shares behind by deleting a shared directory with a trailing slash and then recreating it, exposing new contents through the dormant public share URL.
AI Analysis
Technical Summary
The vulnerability in filebrowser prior to version 2.63.17 involves improper path normalization in the DeleteWithPathPrefix function. Authenticated users can exploit this by deleting a shared directory with a trailing slash path, which fails to properly update the share index. Consequently, stale public shares remain accessible, and attackers can recreate the directory to expose new content via the old public share URL. This issue is tracked as CVE-2026-61874 and is categorized under CWE-863 (Incorrect Authorization).
Potential Impact
Authenticated users can leave stale public shares accessible after deleting shared directories, potentially exposing new content through dormant public share URLs. The impact is limited to exposure of content via stale shares and does not include privilege escalation or remote code execution. The severity is assessed as low.
Mitigation Recommendations
A fix is available in filebrowser version 2.63.17 that addresses the path normalization issue. Users should upgrade to version 2.63.17 or later to remediate this vulnerability. No other mitigations are indicated.
