Last modified

CVE-2026-62684 is a low-severity vulnerability rated 2.7/10 on the CVSS scale. File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.17, the Link storage struct is serialized directly by sharePostHandler, shareListHandler, and shareGetsHandler through renderJSON, causing POST /api/share/{path} and GET /api/shares to expose password_hash and the bypass token, while an administrator can retrieve these secrets for every user's shares, enabling offline password cracking and direct access to protected shares. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
