{"id":"CVE-2026-4365","state":"PUBLISHED","title":"LearnPress <= 4.3.2.8 - Missing Authorization to Unauthenticated Arbitrary Quiz Answer Deletion","description":"The LearnPress plugin for WordPress is vulnerable to unauthorized data deletion due to a missing capability check on the `delete_question_answer()` function in all versions up to, and including, 4.3.2.8. The plugin exposes a `wp_rest` nonce in public frontend HTML (`lpData`) to unauthenticated visitors, and uses that nonce as the only security gate for the `lp-load-ajax` AJAX dispatcher. The `delete_question_answer` action has no capability or ownership check. This makes it possible for unauthenticated attackers to delete any quiz answer option by sending a crafted POST request with a publicly available nonce.","publishedAt":"2026-04-14T01:24:59.735Z","updatedAt":"2026-04-14T13:48:54.581Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["thimpress LearnPress – WordPress LMS Plugin for Create and Sell Online Courses"],"affected":[{"vendor":"thimpress","product":"LearnPress – WordPress LMS Plugin for Create and Sell Online Courses","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.3.2.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/021bd566-1663-46ba-a616-ab554b691cbb?source=cve","https://plugins.trac.wordpress.org/browser/learnpress/trunk/inc/Ajax/EditQuestionAjax.php#L285","https://plugins.trac.wordpress.org/browser/learnpress/trunk/inc/Ajax/AbstractAjax.php#L33","https://plugins.trac.wordpress.org/browser/learnpress/trunk/inc/class-lp-assets.php#L177"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4365.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4365","state":"PUBLISHED","datePublished":"2026-04-14T01:24:59.735Z","dateUpdated":"2026-04-14T13:48:54.581Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-17T20:45:25.774Z"},"containers":{"cna":{"title":"LearnPress <= 4.3.2.8 - Missing Authorization to Unauthenticated Arbitrary Quiz Answer Deletion","descriptions":[{"lang":"en","value":"The LearnPress plugin for WordPress is vulnerable to unauthorized data deletion due to a missing capability check on the `delete_question_answer()` function in all versions up to, and including, 4.3.2.8.
