HIGH

File Browser share links remain accessible after Share/Download permissions are revoked

Title source: cna
STIX 2.1

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, when an admin revokes a user's Share and Download permissions, existing share links created by that user remain fully accessible to unauthenticated users. The public share download handler does not re-check the share owner's current permissions. This vulnerability is fixed in 2.63.1.
