This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with subscriber-level permissions or above to change user passwords and potentially take over administrator accounts.","publishedAt":"2023-09-13T02:54:11.287Z","updatedAt":"2026-04-08T16:59:33.273Z","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":["mpvanwinkle77 Simplr Registration Form Plus+"],"affected":[{"vendor":"mpvanwinkle77","product":"Simplr Registration Form Plus+","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.4.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6ddf0452-3afe-4ada-bccc-30c818968a81?source=cve","https://plugins.trac.wordpress.org/browser/simplr-registration-form/trunk/lib/profile.php#L148"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:06:33.064Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/4xxx/CVE-2023-4213.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2023-4213","state":"PUBLISHED","datePublished":"2023-09-13T02:54:11.287Z","dateUpdated":"2026-04-08T16:59:33.273Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2023-08-07T18:53:50.546Z"},"containers":{"cna":{"title":"Simplr Registration Form Plus+ <= 2.4.5 - Authenticated (Subscriber+) Insecure Direct Object Reference to Arbitrary User Password Change","descriptions":[{"lang":"en","value":"The Simplr Registration Form Plus+ plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 2.4.5.
