Unauthenticated Broken Access Control in Ad Invalid Click Protector (AICP) <= 1.3.0 versions.
AnalysisAI
Broken access control in the Ad Invalid Click Protector (AICP) WordPress plugin up to version 1.3.0 allows unauthenticated attackers to manipulate plugin settings or disrupt its click-protection functionality. No active exploitation or public proof-of-concept is currently known, but the vulnerability is easily triggered over the network with no user interaction.
Technical ContextAI
This is a missing authorization flaw (CWE-862) in the AICP plugin for WordPress, which is designed to block invalid ad clicks. The vulnerable endpoint likely lacks proper access controls for REST API endpoints or admin-ajax actions, permitting unauthenticated request handling. The CPE is not officially assigned, but the plugin slug 'ad-invalid-click-protector' and affected versions ≤1.3.0 are confirmed by the Patchstack advisory.
RemediationAI
No specific patched version has been confirmed at the time of this analysis; check the vendor’s Patchstack page for updates. If no update is available, immediately deactivate the plugin or use a Web Application Firewall rule to block unauthenticated requests to plugin endpoints (e.g., paths containing ‘aicp’). Deactivation removes the vulnerability entirely but also stops all ad click protection.
