Doc Text:
A flaw was found in Gitea. The Fork-PR Actions task, which handles pull requests from forked repositories, can be exploited to read data from a third private repository. This occurs due to a missing guard that should prevent unauthorized access via the collaborative-owner branch. A remote attacker could leverage this vulnerability to gain unauthorized access to sensitive information.
