Overview
Affected versions of this package are vulnerable to Incorrect Authorization due to improper access control in the unaccess process. An attacker can cause disruption of all public shares routed through a global frontend by sending a DELETE request to the affected API endpoint with knowledge of a valid global frontend token. This is only exploitable if the attacker possesses a global frontend token, which is not accessible through standard API endpoints and must be obtained through out-of-band methods such as leaked logs or social engineering.
