AI Analysis
Technical Summary
CVE-2025-10293 is an improper authentication vulnerability (CWE-287) in the Keyy Two Factor Authentication plugin for WordPress, versions up to 1.2.3. The plugin fails to properly validate the user identity associated with generated authentication tokens. This flaw allows authenticated attackers with subscriber-level privileges or higher to generate valid tokens and impersonate other users, including administrators with 2FA enabled, effectively escalating their privileges. The vulnerability has a CVSS 3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating a high-impact remote attack with low complexity and no user interaction required.
Potential Impact
An attacker with at least subscriber-level access can bypass proper authentication checks to impersonate other users, including administrators who have two-factor authentication enabled. This leads to full compromise of affected WordPress sites, impacting confidentiality, integrity, and availability of the system. The vulnerability enables privilege escalation and account takeover without requiring user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix is indicated, administrators should monitor the vendor's communications for updates. Until a fix is available, consider disabling the Keyy Two Factor Authentication plugin or restricting access to trusted users only to reduce risk.
