WordPress · Web Performance Monitor · CVE-2026-3881
**Name of the Vulnerable Software and Affected Versions**
Performance Monitor WordPress plugin versions through 1.0.6
**Description**
The Performance Monitor WordPress plugin does not properly validate a parameter before using it in a request, potentially allowing unauthenticated users to carry out Server-Side Request Forgery (SSRF) attacks. SSRF attacks occur when an attacker can cause the server to make requests to unintended locations, potentially exposing sensitive data or performing actions on behalf of the server. The vulnerable parameter is not specified.
**Recommendations**
Update the Performance Monitor WordPress plugin to a version later than 1.0.6.
