Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-862.
Summary
The WP Encryption WordPress plugin before 7.8.8.2 lacks a capability or nonce check on one of the handlers that drives its SSL certificate-provisioning routine (CWE-862). An unauthenticated remote attacker can make a single request to overwrite the site's certificate private key and replace its pending Let's Encrypt order and challenge material. Repeated requests keep regenerating this material, which prevents the administrator from completing certificate issuance. A public exploit is linked in the references.
