What is CVE-2025-52996?
CVE-2025-52996 is a low-severity authentication bypass vulnerability in filebrowser, published on 30 Jun 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. In versions 2.32.0 and prior, the implementation of password protected links is error-prone, resulting in potential unprotected sharing of a file through a direct download link. This link can either be shared unknowingly by a user or discovered from various locations such as the browser history or the log of a proxy server used. At time of publication, no known patched versions are available.
