CVE-2025-69394: 
WordPress vulnerability analysis and mitigation

CVE-2025-69394 is an Authorization Bypass Through User-Controlled Key (IDOR) vulnerability in the Cnvrse WordPress plugin by cnvrse. It allows unauthenticated remote attackers to access sensitive information by exploiting incorrectly configured access control security levels. The vulnerability affects Cnvrse versions from n/a through versions prior to 026.02.10.20. It carries a CVSS v3.1 base score of 7.5 (High), with high confidentiality impact and no authentication required (Feedly).

The root cause is classified as CWE-639 (Authorization Bypass Through User-Controlled Key), commonly known as an Insecure Direct Object Reference (IDOR). An attacker can manipulate user-controlled keys or identifiers in requests to bypass access controls and retrieve resources belonging to other users or privileged contexts. The attack vector is network-based, requires no authentication, no user interaction, and low attack complexity, making it trivially exploitable against any exposed instance of the plugin (Feedly).

Successful exploitation results in unauthorized access to sensitive data protected by the plugin's access controls, with a high confidentiality impact. Integrity and availability are not directly affected by this vulnerability. Depending on the data managed by the Cnvrse plugin, exposed information could include user data, private content, or configuration details stored within the WordPress installation (Feedly).

The vulnerability requires no authentication and no user interaction, making it accessible to any remote attacker. The EPSS score is approximately 0.017% (0.000170), indicating a currently low probability of active exploitation in the wild. No public proof-of-concept exploit code, exploit kit integration, threat actor attribution, or CISA KEV catalog listing has been identified for this CVE at this time (Feedly).

1. Reconnaissance: Identify WordPress sites running the Cnvrse plugin (versions prior to 026.02.10.20) using tools like WPScan, Shodan, or Google dorks targeting plugin-specific file paths.
2. Enumerate object identifiers: Observe or guess user-controlled keys (e.g., numeric IDs, UUIDs) used in plugin API requests or URL parameters that reference protected resources.
3. Craft malicious request: Send unauthenticated HTTP requests to the vulnerable plugin endpoint, substituting the object identifier with values belonging to other users or privileged resources.
4. Extract sensitive data: Review the server's response for unauthorized data disclosure, such as private user records, restricted content, or configuration details managed by the plugin (Feedly).

• Network: Unusual unauthenticated HTTP GET or POST requests to Cnvrse plugin endpoints with sequential or enumerated object ID parameters from a single IP address.
• Logs: WordPress access logs showing repeated requests to plugin-specific URLs (e.g., paths under /wp-content/plugins/cnvrse/) with varying ID values and no associated authenticated session cookies.
• Logs: HTTP 200 responses to requests that should require authentication, particularly for resource retrieval endpoints of the Cnvrse plugin.

Users should update the Cnvrse plugin to version 026.02.10.20 or later, which addresses the access control misconfiguration. Until patching is possible, consider disabling the plugin on publicly accessible WordPress installations or restricting access to the WordPress site via IP allowlisting. Regularly audit WordPress plugin versions and apply updates promptly to minimize exposure (Feedly).
