CVE-2026-104006 | BDVDB-2026-385446 Detail
softaculousSpeedyCache – Cache, Optimization, Performance
Description#
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 'comment_author_*, comment_author_email_*' 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 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.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact none, availability impact none. Attack vector: network.
Weaknesses#
- CWE-524 Use of Cache Containing Sensitive Information
