Medium (5.4) in filebrowser filebrowser. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/gtsteffaniak/filebrowser 0.0.0-20260307130210-09713b32a5f6.
FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to 1.3.1-beta and 1.2.2-stable, Stored XSS is possible via share metadata fields (e.g., title, description) that are rendered into HTML for /public/share/<hash> without context-aware escaping. The server uses text/template instead of html/template, allowing injected scripts to execute when victims visit the share URL. This vulnerability is fixed in 1.3.1-beta and 1.2.2-stable.
