Authentication Bypass in OwnID Passwordless Login for WordPress
CVE-2025-10294 is a critical authentication bypass vulnerability in the OwnID Passwordless Login plugin for WordPress affecting all versions up to and including 1.3.4. The flaw is caused by improper validation of the ownid_shared_secret value during JWT-based authentication. Specifically, the plugin does not properly verify that ownid_shared_secret is set and non-empty before processing authentication tokens. On instances where the plugin is installed but not fully configured, an attacker can supply a forged JWT with arbitrary claims, such as a target user identifier, and the plugin may accept it and authenticate the attacker as that user. This can result in unauthorized login as any account, including administrator accounts.
