Description

This security bulletin contains information about 1 vulnerability.


1) Incorrect authorization (CVE-ID: N/A)

CWE-ID: CWE-863 - Incorrect Authorization

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to incorrect authorization in the public share cleanup logic in storage/bolt/share.go when deleting a shared directory through a trailing-slash path. A remote user can create a public share and send an authenticated delete request for the shared directory path with a trailing slash to disclose sensitive information.

The stale public share remains dormant until a directory at the same path is recreated, after which the old public URL exposes the new directory contents without authentication.


Remediation

Install update from vendor's website.
