Incorrect Privilege Assignment vulnerability in pebas CouponXxL Custom Post Types allows Privilege Escalation. This issue affects CouponXxL Custom Post Types: from n/a through 3.0.
AnalysisAI
Privilege escalation in the CouponXxL Custom Post Types WordPress plugin (version ≤3.0) allows unauthenticated attackers to gain higher-level permissions due to incorrect privilege assignment. No active exploitation or public exploit code is known; EPSS predicts a 0.08 % probability of exploitation activity.
Technical ContextAI
The vulnerability is a CWE-266 flaw in the plugin's privilege management, likely resulting from improper capability checks or role mapping when handling custom post types. The CVSS vector AV:N/AC:L/PR:N/UI:N indicates network-level, unauthenticated exploitation with no user interaction; successful abuse yields high confidentiality impact, moderate integrity/availability impact. Affected versions were listed by EUVD as up to and including 3.0.
RemediationAI
No vendor-released patch has been identified at the time of analysis. As an immediate mitigation, deactivate and remove the CouponXxL Custom Post Types plugin until an official fix is published. If removal is not feasible, restrict administrative access to trusted users and monitor the WordPress database for unauthorized role changes, though these are only supplementary measures and do not address the root vulnerability.
