Overview
Affected versions of this package are vulnerable to Incorrect Authorization through the UpdatePullRequest function. An attacker can cause unauthorized modifications to private repository branches by exploiting a logic flaw in token scope validation during pull request updates from a public base repository.
Note: This is only exploitable if the attacker possesses a valid public-only,write:repository token for a user with write access to the private pull request head branch, and there exists a public base repository with an open pull request targeting the private head branch.
