CVE-2025-62952

Vulnerability

Overview

The QuantumCloud ChatBot plugin for WordPress contains a missing authorization vulnerability (CVE-2025-62952) affecting versions from n/a through 7.7.3. This bug allows exploitation of incorrectly configured access control security levels, meaning certain functions lack proper authorization checks [1].

Attack

Vector

Because the plugin fails to validate user permissions on every request whether the user is authenticated and has sufficient privileges, unauthenticated attackers or low-privilege users can perform actions intended only for administrators. The vulnerability is classified as broken access control, where missing authorization or nonce token checks enable an unprivileged user to execute higher-privileged actions externally [1].

Impact

Successful exploitation could allow an attacker to bypass security restrictions, potentially modifying chatbot settings or interacting with protected plugin functionality. While the severity is rated Medium (CVSS 4.3) and considered low impact, such vulnerabilities are often used in mass-exploit campaigns targeting thousands of WordPress sites [1].

Mitigation

The vendor has released version 7.7.4.0? (note: reference says 7.7.4 in text but numeric discrepancy exists — referencing exactly what source says: “Update to version 7.7.4 or later”). Users should update immediately. Patchstack users can enable auto-updates for vulnerable plugins [1].
