{"id":"CVE-2026-3523","state":"PUBLISHED","title":"Apocalypse Meow <= 22.1.0 - Authenticated (Administrator+) SQL Injection via 'type' Parameter","description":"The Apocalypse Meow plugin for WordPress is vulnerable to SQL Injection via the 'type' parameter in all versions up to, and including, 22.1.0. This is due to a flawed logical operator in the type validation check on line 261 of ajax.php — the condition uses `&&` (AND) instead of `||` (OR), causing the `in_array()` validation to be short-circuited and never evaluated for any non-empty type value. Combined with `stripslashes_deep()` being called on line 101 which removes `wp_magic_quotes()` protection, attacker-controlled single quotes pass through unescaped into the SQL query on line 298. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.","publishedAt":"2026-03-05T04:21:53.356Z","updatedAt":"2026-04-08T17:12:30.229Z","severity":{"score":4.9,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["blobfolio Apocalypse Meow"],"affected":[{"vendor":"blobfolio","product":"Apocalypse Meow","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"22.1.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a1af9757-23e9-41d2-bbcd-15b0610b6538?source=cve","https://plugins.trac.wordpress.org/browser/apocalypse-meow/trunk/lib/blobfolio/wp/meow/ajax.php#L298","https://plugins.trac.wordpress.org/browser/apocalypse-meow/tags/22.1.0/lib/blobfolio/wp/meow/ajax.php#L298","https://plugins.trac.wordpress.org/browser/apocalypse-meow/trunk/lib/blobfolio/wp/meow/ajax.php#L261","https://plugins.trac.wordpress.org/browser/apocalypse-meow/tags/22.1.0/lib/blobfolio/wp/meow/ajax.php#L261","https://plugins.trac.wordpress.org/browser/apocalypse-meow/trunk/lib/blobfolio/wp/meow/ajax.php#L101","https://plugins.trac.wordpress.org/browser/apocalypse-meow/tags/22.1.0/lib/blobfolio/wp/meow/ajax.php#L101","https://plugins.trac.wordpress.org/browser/apocalypse-meow/trunk/lib/blobfolio/wp/meow/ajax.php#L167","https://plugins.trac.wordpress.org/browser/apocalypse-meow/tags/22.1.0/lib/blobfolio/wp/meow/ajax.php#L167","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3448958%40apocalypse-meow&new=3448958%40apocalypse-meow&sfp_email=&sfph_mail="],"weaknesses":["CWE-89"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/3xxx/CVE-2026-3523.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-3523","state":"PUBLISHED","datePublished":"2026-03-05T04:21:53.356Z","dateUpdated":"2026-04-08T17:12:30.229Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-04T16:04:52.755Z"},"containers":{"cna":{"title":"Apocalypse Meow <= 22.1.0 - Authenticated (Administrator+) SQL Injection via 'type' Parameter","descriptions":[{"lang":"en","value":"The Apocalypse Meow plugin for WordPress is vulnerable to SQL Injection via the 'type' parameter in all versions up to, and including, 22.1.0.
