{"id":"CVE-2026-4123","state":"PUBLISHED","title":"RW Elephant Rental Inventory <= 2.3.13 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'toggle_cache' AJAX Action","description":"The RW Elephant Rental Inventory plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 2.3.13. This is due to a missing capability check on the toggle_cache() function which is hooked to the wp_ajax_toggle_cache AJAX action. The function also lacks nonce verification. This makes it possible for authenticated attackers, with Subscriber-level access and above, to toggle the plugin's cache setting on or off by sending a POST request to admin-ajax.","publishedAt":"2026-09-22T07:41:11.190Z","updatedAt":"2026-09-22T10:25:32.464Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["rwelephant01 RW Elephant Rental Inventory"],"affected":[{"vendor":"rwelephant01","product":"RW Elephant Rental Inventory","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.3.13","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/5e46beca-e33b-4ed9-a0ab-612a6987174e?source=cve","https://plugins.trac.wordpress.org/browser/rw-elephant-rental-inventory/trunk/lib/classes/class-options.php#L1524","https://plugins.trac.wordpress.org/browser/rw-elephant-rental-inventory/tags/2.3.11/lib/classes/class-options.php#L1524","https://plugins.trac.wordpress.org/browser/rw-elephant-rental-inventory/trunk/lib/classes/class-options.php#L75","https://plugins.trac.wordpress.org/browser/rw-elephant-rental-inventory/tags/2.3.11/lib/classes/class-options.php#L75","https://plugins.trac.wordpress.org/changeset/3551183"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4123.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4123","state":"PUBLISHED","datePublished":"2026-09-22T07:41:11.190Z","dateUpdated":"2026-09-22T10:25:32.464Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-13T13:37:50.598Z"},"containers":{"cna":{"title":"RW Elephant Rental Inventory <= 2.3.13 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'toggle_cache' AJAX Action","descriptions":[{"lang":"en","value":"The RW Elephant Rental Inventory plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 2.3.13.
