CVE-2026-62684

File Browser: Share API exposes the password hash and bypass token

Published Aug 18, 2026 CVSS 3.1 · 2.7 Low EPSS < 1% KEV · Not listed
Description
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. This issue is fixed in version 2.63.17.
