The SpeedyCache – Cache, Optimization, Performance plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.4.2 via the 'commentauthor, commentauthoremail' parameter. 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 commentauthor 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.

The Password Protected plugin for WordPress is vulnerable to authorization bypass via IP address spoofing in all versions up to, and including, 2.7.11. This is due to the plugin trusting client-controlled HTTP headers (such as X-Forwarded-For, HTTPCLIENTIP, and similar headers) to determine user IP addresses in the ppgetipaddress() function when the "Use transients" feature is enabled. This makes it possible for attackers to bypass authorization by spoofing these headers with the IP address of a legitimately authenticated user, granted the "Use transients" option is enabled (non-default configuration) and the site is not behind a CDN or reverse proxy that overwrites these headers.
