Overview
Affected versions of this package are vulnerable to Missing Authorization in the attachment update. An attacker can access private attachment content by re-linking a known attachment UUID to an issue or comment in a repository they control, causing authorization checks to be performed against the attacker's repository context rather than the original, potentially private, repository.
