This is due to missing authorization checks in the `ajax_coupon_details()` function, which only validates nonces but does not verify user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve sensitive coupon information including coupon codes, discount amounts, usage statistics, and course/bundle applications.","publishedAt":"2026-02-03T07:31:23.720Z","updatedAt":"2026-04-08T17:03:21.310Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["themeum Tutor LMS – eLearning and online course solution"],"affected":[{"vendor":"themeum","product":"Tutor LMS – eLearning and online course solution","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.9.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/7f5c5f64-a864-4ce1-9080-19f7c4418307?source=cve","https://plugins.trac.wordpress.org/browser/tutor/tags/3.9.5/ecommerce/CouponController.php#L106","https://plugins.trac.wordpress.org/browser/tutor/tags/3.9.5/ecommerce/CouponController.php#L658","https://plugins.trac.wordpress.org/changeset/3448615/tutor/trunk/ecommerce/CouponController.php?contextall=1&old=3422766&old_path=%2Ftutor%2Ftrunk%2Fecommerce%2FCouponController.php"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1371.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1371","state":"PUBLISHED","datePublished":"2026-02-03T07:31:23.720Z","dateUpdated":"2026-04-08T17:03:21.310Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-23T16:00:38.156Z"},"containers":{"cna":{"title":"Tutor LMS <= 3.9.5 - Authenticated (Subscriber+) Information Disclosure in Coupon Details via 'tutor_coupon_details' AJAX Action","descriptions":[{"lang":"en","value":"The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.9.5.
