What is CVE-2026-8293?

The Really Simple Security plugin for WordPress, prior to version 9.5.10.1, inadequately implements the second-factor authentication challenge in its REST endpoints. This flaw allows attackers who have compromised a user's password to bypass the email OTP requirement, enabling them to gain unauthorized access to the user's WordPress session without entering the one-time password. Securing this plugin is essential to maintain robust user authentication and prevent unauthorized access.

Affected Version(s)

Really Simple Security 0 < 9.5.10.1

Exploit Proof of Concept (PoC)
