CVE-2026-35607 Details
Description
File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.1, the fix in commit b6a4fb1 ("self-registered users don't get execute perms") stripped Execute permission and Commands from users created via the signup handler. The same fix was not applied to the proxy auth handler. Users auto-created on first successful proxy-auth login are granted execution capabilities from global defaults, even though the signup path was explicitly changed to prevent execution rights from being inherited by automatically provisioned accounts. This vulnerability is fixed in 2.63.1.
A vulnerability in File Browser prior to version 2.63.1 allows users auto-created through the proxy authentication process to inherit execution permissions and commands from global defaults. This issue arises because the proxy authentication handler does not apply the same restrictions as the signup handler, which prevents self-registered users from receiving execution rights. As a result, automatically provisioned accounts via proxy authentication can execute commands that were not explicitly granted by an administrator.
Users can update to File Browser version 2.63.1, where this vulnerability has been fixed.
