CVE-2025-10294: Victornavarro Ownid Passwordless Login

Critical severity, CVSS 9.8. EPSS: 0.8% chance of exploitation in the next 30 days.

The OwnID Passwordless Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.3.4. This is due to the plugin not properly checking if the ownid_shared_secret value is empty prior to authenticating a user via JWT. This makes it possible for unauthenticated attackers to log in as other users, including administrators, on instances where the plugin has not been fully configured yet.
