{"id":"CVE-2026-6020","state":"PUBLISHED","title":"ShopLentor <= 3.3.7 - Authenticated (Administrator+) Arbitrary Function Execution via 'callback' Parameter via REST API","description":"The ShopLentor plugin for WordPress is vulnerable to arbitrary function execution via the woolentoropt/v1/custom-action REST API endpoint in all versions up to, and including, 3.3.7. This is due to the handle_action() method passing user-supplied input directly to call_user_func() without an allowlist of permitted callbacks. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute arbitrary PHP callable functions via the 'callback' parameter.","publishedAt":"2026-08-05T07:39:20.379Z","updatedAt":"2026-08-05T14:17:21.846Z","severity":{"score":7.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["devitemsllc ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin"],"affected":[{"vendor":"devitemsllc","product":"ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.3.7","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/00138875-d892-460c-b0ce-7a01335d26dc?source=cve","https://plugins.trac.wordpress.org/browser/woolentor-addons/trunk/includes/admin-panel/includes/classes/Api/Custom_Actions.php#L99","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3504292%40woolentor-addons%2Ftrunk&old=3493678%40woolentor-addons%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-470"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6020.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6020","state":"PUBLISHED","datePublished":"2026-08-05T07:39:20.379Z","dateUpdated":"2026-08-05T14:17:21.846Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-09T15:37:55.489Z"},"containers":{"cna":{"title":"ShopLentor <= 3.3.7 - Authenticated (Administrator+) Arbitrary Function Execution via 'callback' Parameter via REST API","descriptions":[{"lang":"en","value":"The ShopLentor plugin for WordPress is vulnerable to arbitrary function execution via the woolentoropt/v1/custom-action REST API endpoint in all versions up to, and including, 3.3.7.
