11th percentile - higher than 11% of all known CVEs

Summary

The Anton Extensions WordPress plugin through 1.2.2 does not perform any capability check, nonce verification, or file-type validation before writing attacker-supplied content to an attacker-chosen path. This allows unauthenticated attackers to upload arbitrary PHP files and achieve remote code execution.

Risk Assessment

An unauthenticated attacker can upload and execute arbitrary PHP code on the server, leading to full compromise of the WordPress site and potentially the entire server.

Recommendation

Immediately remove or update the Anton Extensions plugin to a version newer than 1.2.2 if available. If no fix exists, disable and remove the plugin.
