CVE-2026-110135: CWE-287 Improper Authentication in OTP Login & Register Woocommerce
Description
The OTP Login & Register Woocommerce WordPress plugin before 2.7.3 does not adequately limit one-time-password verification attempts, because the attempt limit is tracked against a value the client itself supplies and can change freely, allowing an unauthenticated attacker to bypass the limit and brute-force the short numeric login code to take over an account without its password.

Technical Analysis
CVE-2026-110135 describes an improper authentication vulnerability (CWE-287) in the OTP Login & Register Woocommerce WordPress plugin prior to version 2.7.3. The vulnerability arises because the plugin tracks OTP verification attempts based on a value provided by the client, which can be freely changed. This design flaw enables an attacker without authentication to bypass the intended limit on OTP verification attempts and brute-force the short numeric OTP. Successful exploitation could lead to account takeover without requiring the victim's password.
Potential Impact
An unauthenticated attacker can bypass the OTP attempt limit and brute-force the OTP code, potentially gaining unauthorized access to user accounts. This compromises account security by allowing attackers to bypass authentication controls and take over accounts without passwords.
Mitigation Recommendations
Upgrade the OTP Login & Register Woocommerce plugin to version 2.7.3 or later, where this vulnerability is fixed. No other mitigation is indicated. Patch status is confirmed by the version boundary in the affectedVersions field.
