A critical broken access control vulnerability in the Post My CF7 Form plugin allows unauthenticated attackers to bypass authorization, creating a high risk of unauthorized data handling.

The vulnerability is identified as CWE-862, indicating a failure to perform adequate authorization checks on sensitive functions. This allows unauthenticated users to access or manipulate form data processing.

The ability for unauthenticated users to bypass access controls can result in unauthorized data exposure or the illegitimate submission of forms. With a CVSS score of 7.5, the impact is significant, potentially compromising the integrity of user-submitted data and internal workflows.

Immediate Action: Update the Post My CF7 Form plugin to version 7.0.0 or later to implement the necessary authorization controls.

Proactive Monitoring: Monitor server access logs for unauthorized attempts to access plugin-specific endpoints or form processing functions.

Compensating Controls: Utilize a Web Application Firewall to filter traffic and restrict access to administrative or sensitive plugin endpoints, reducing the attack surface.

Public Exploit Available: No

Immediate remediation is required to secure the plugin against unauthorized access. Administrators must ensure that the update to version 7.0.0 is applied promptly to mitigate the risk of data compromise.
