Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass / Access Control: The workflow triggers on issue comments referencing pull requests, and the fix removed an explicit author_association check, shifting authorization to an external maintainer-tools action. If that action is misconfigured or bypassed, unauthorized users could trigger snapshot updates.

Path Traversal / Arbitrary File Access: The getDownloadUrl sink for local image paths was replaced with a placeholder data URI, preventing disclosure of arbitrary local files via markdown rendering. Without this sanitization, a crafted markdown could reference any local file path.
