CVE-2026-4123
RW Elephant Rental Inventory <= 2.3.13 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'toggle_cache' AJAX Action
CVSS Score

EPSS Percentile
0th
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.
