CVE-2026-8293: CWE-287 Improper Authentication in Really Simple Security
CVE-2026-8293 is an authentication bypass vulnerability in the Really Simple Security WordPress plugin versions before 9. 5. 10. 1. The plugin fails to enforce the second-factor challenge on two of its two-factor authentication REST endpoints. This allows an attacker who already knows a user's password to obtain a valid WordPress authentication session without completing the required email OTP challenge.
AI Analysis
Technical Summary
The Really Simple Security WordPress plugin prior to version 9.5.10.1 contains an improper authentication vulnerability (CWE-287) where two REST endpoints related to two-factor authentication do not enforce the second-factor email OTP challenge. An attacker with knowledge of a user's password can bypass the second factor and gain an authenticated session, effectively bypassing the intended two-factor authentication protection.
Potential Impact
An attacker who knows a user's password can bypass the second-factor authentication step and gain unauthorized access to the user's WordPress session. This undermines the security benefits of two-factor authentication and could lead to account compromise. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability affects versions before 9.5.10.1, upgrading to version 9.5.10.1 or later (if available) is recommended once confirmed. Until a patch or official fix is available, consider disabling the affected two-factor authentication REST endpoints or implementing additional access controls to prevent exploitation.
