{"id":"CVE-2026-1929","state":"PUBLISHED","title":"Advanced Woo Labels <= 2.37 - Authenticated (Contributor+) Remote Code Execution via 'callback' Parameter","description":"The Advanced Woo Labels plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.37. This is due to the use of `call_user_func_array()` with user-controlled callback and parameters in the `get_select_option_values()` AJAX handler without an allowlist of permitted callbacks or a capability check. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute arbitrary PHP functions and operating system commands on the server via the 'callback' parameter.","publishedAt":"2026-02-25T08:25:31.823Z","updatedAt":"2026-04-08T17:18:33.467Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["mihail-barinov Advanced Woo Labels – Product Labels & Badges for WooCommerce"],"affected":[{"vendor":"mihail-barinov","product":"Advanced Woo Labels – Product Labels & Badges for WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.36","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/bbae9c33-becb-4c9d-917f-0d8fe8312d0c?source=cve","https://plugins.trac.wordpress.org/browser/advanced-woo-labels/tags/2.34/includes/admin/class-awl-admin-ajax.php#L136","https://plugins.trac.wordpress.org/browser/advanced-woo-labels/tags/2.34/includes/admin/class-awl-admin-ajax.php#L146","https://plugins.trac.wordpress.org/browser/advanced-woo-labels/trunk/includes/admin/class-awl-admin-ajax.php#L146","https://plugins.trac.wordpress.org/browser/advanced-woo-labels/tags/2.37/includes/admin/class-awl-admin-ajax.php#L136"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1929.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1929","state":"PUBLISHED","datePublished":"2026-02-25T08:25:31.823Z","dateUpdated":"2026-04-08T17:18:33.467Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-04T20:28:59.180Z"},"containers":{"cna":{"title":"Advanced Woo Labels <= 2.37 - Authenticated (Contributor+) Remote Code Execution via 'callback' Parameter","descriptions":[{"lang":"en","value":"The Advanced Woo Labels plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.37.
