What is CVE-2026-35604?

The vulnerability in File Browser relates to improper handling of user permissions regarding file sharing. When an administrator revokes a user's share and download permissions, any existing share links created by that user remain accessible to unauthenticated users, leading to potential unauthorized access to sensitive data. The issue arises because the public share download handler does not verify the current permissions of the share owner. This security flaw can result in unintentional exposure of files even after permission changes are made. The vulnerability was remedied in version 2.63.1, which addresses these critical permission checks.

Affected Version(s)
