AI Analysis

Impact

The ChamaWP WordPress plugin versions prior to 1.0.13 lack proper validation for password reset requests. This flaw lets anyone who can reach the reset endpoint set a new password for any user—including administrators—without authentication. If an attacker gains such control, they can take complete control of the site and its data.

Affected Systems

WordPress sites using the ChamaWP plugin with any release before 1.0.13 are affected. No specific version numbers beyond the "less than 1.0.13" boundary are listed in the CNA data. Site administrators should verify the installed plugin version and treat all earlier releases as vulnerable.

Risk and Exploitability

The attack can be carried out remotely over HTTP/HTTPS without authentication, making it readily exploitable by public or hidden actors. The CVSS score is 9.8. EPSS score is < 1%, indicating a very low probability of exploitation. The vulnerability is not listed in the CISA KEV catalog, yet its simplicity and impact warrant immediate attention.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update ChamaWP to version 1.0.13 or newer. If an update is unavailable, remove or disable the plugin entirely.
  • Implement a temporary web‑application firewall rule or .htaccess restriction to block unauthenticated requests to the password‑reset endpoint.
  • Ensure that users enforce strong, unique passwords and change them regularly.
