CVE-2026-89080: CWE-287 Improper Authentication in Really Simple Security
The Really Simple Security WordPress plugin before 9.8.1 does not prevent an unauthenticated request from resetting an account's completed email two-factor enrolment, allowing an attacker who already knows the account's password to bypass the second factor and obtain that user's session, up to administrator.
AI Analysis
Technical Summary
The Really Simple Security WordPress plugin versions from 9.5.10.1 up to but not including 9.8.1 contain an improper authentication vulnerability (CWE-287). The plugin does not prevent unauthenticated requests from resetting an account's completed email two-factor authentication enrollment. An attacker with knowledge of the account password can exploit this to bypass the second factor and obtain the user's session, potentially escalating privileges to administrator.
Potential Impact
Successful exploitation allows an attacker who already knows a user's password to bypass two-factor authentication and hijack the user's session. This can lead to full account compromise, including administrator-level access, resulting in complete control over the affected WordPress site.
Mitigation Recommendations
Upgrade the Really Simple Security plugin to version 9.8.1 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is documented. Patch status is confirmed by the version range affected and fixed in 9.8.1.
