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.","state":0,"publishedAt":"2026-10-10T06:40:15.885+00:00","modifiedAt":"2026-10-11T16:55:16.112+00:00","affected":[{"ecosystem":"Vendor product","name":"SpeedyCache – Cache, Optimization, Performance","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"softaculous\",\n                    \"product\": \"SpeedyCache – Cache, Optimization, Performance\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.4.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7,"severity":"LOW"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/c6b8d5ca-34e2-4d25-9185-7fcee790379d?source=cve","https://plugins.trac.wordpress.org/browser/speedycache/tags/1.4.2/main/cache.php#L151","https://plugins.trac.wordpress.org/browser/speedycache/tags/1.4.2/main/cache.php#L91","https://plugins.trac.wordpress.org/browser/speedycache/tags/1.4.2/main/cache.php#L214","https://plugins.trac.wordpress.org/browser/speedycache/tags/1.4.2/main/advanced-cache.php#L108","https://plugins.trac.wordpress.org/changeset/3734609/speedycache","https://plugins.trac.wordpress.org/changeset/3734608/speedycache/trunk/main/cache.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104006","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104006","identifiers":["CVE-2026-104006"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
