CVE-2026-15210 Details
Description
The OTP Login With Phone Number, OTP Verification WordPress plugin before 1.8.71 does not limit the number of OTP verification attempts or invalidate a one-time login code after a wrong guess, and an unauthenticated user can request a login code for any account. Because the code is a short numeric OTP, an attacker can brute-force it and take over any account, including an administrator's.
A vulnerability exists in the OTP Login With Phone Number, OTP Verification WordPress plugin in versions prior to 1.8.71. The plugin fails to limit the number of OTP verification attempts and does not invalidate a one-time login code after a failed attempt. This allows an unauthenticated user to request a login code for any account. Since the OTP is a short numeric code, an attacker can brute-force it, potentially gaining access to any account, including those of administrators.
Users are advised to update the OTP Login With Phone Number, OTP Verification WordPress plugin to version 1.8.71 or later.
