CVE-2025-62116: 
WordPress vulnerability analysis and mitigation

CVE-2025-62116 is a Missing Authorization vulnerability in the Quadlayers AI Copilot WordPress plugin that allows unauthenticated network attackers to exploit incorrectly configured access control security levels. The vulnerability was initially disclosed on December 31, 2025, and affects AI Copilot versions through 1.4.7 (originally reported), later updated to include versions through 1.5.2. It carries a CVSS v3.1 base score of 5.3 (Medium), assigned by Patchstack (Patchstack, Red Hat CVE).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to properly verify whether a requesting user has the necessary permissions before performing sensitive operations. The attack vector is network-based, requires no authentication, no user interaction, and low attack complexity, making it trivially exploitable by any unauthenticated remote attacker. The vulnerability stems from incorrectly configured access control security levels within the AI Copilot plugin's WordPress REST API endpoints or AJAX handlers, allowing unauthorized data modification (Patchstack, Red Hat CVE).

Successful exploitation allows unauthenticated attackers to perform unauthorized data modification (integrity impact: Low), though confidentiality and availability are not directly impacted per the CVSS assessment. In a WordPress context, broken access control in an AI plugin could allow attackers to alter plugin settings, manipulate AI-generated content, or interfere with plugin functionality without any credentials. The scope is limited to the affected WordPress installation running the vulnerable plugin version (Patchstack).

No public proof-of-concept exploit code or evidence of active in-the-wild exploitation has been reported for this vulnerability. The EPSS score is approximately 0.028% (0.000280), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, and no threat actor attribution has been identified (Red Hat CVE).

Users should update the Quadlayers AI Copilot WordPress plugin to a version beyond 1.5.2 (the last known vulnerable version as of the most recent CVE update). Site administrators should monitor the official WordPress plugin repository or the Quadlayers vendor page for a patched release. As a temporary workaround, consider deactivating the plugin until a fix is confirmed available, or restricting access to the WordPress site's REST API endpoints for unauthenticated users where feasible (Patchstack).
