CVE-2026-108064 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. The WP Encryption WordPress plugin before 7.8.8.2 does not perform a capability or nonce check on one of the handlers that drives its SSL certificate-provisioning routine, allowing unauthenticated users to make the WP Encryption WordPress plugin before 7.8.8.2 overwrite the site's certificate private key and replace its pending Let's Encrypt order and challenge material with a single request. Repeated requests keep regenerating the material, preventing the administrator from completing certificate issuance.. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
