This makes it possible for unauthenticated attackers to extract the full name and email address of returning commenters pre-filled into comment form input fields and persisted as the site-wide cached page by any unauthenticated attacker requesting the same public URL. The read-side handler in advanced-cache.php correctly skips cached delivery for requests carrying comment_author_* cookies, but this check is absent on the write path, meaning the cache poisoning is invisible to the victim commenter yet fully exploitable by any unauthenticated attacker with no cookies.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":20,"depthScoreParts":{"impact":20.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
