 "title": "OTP Login With Phone Number, OTP Verification <= 1.8.74 - Unauthenticated Authentication Bypass via OTP Brute Force",
 "description": "The OTP Login With Phone Number, OTP Verification plugin for WordPress is vulnerable to authentication bypass via OTP brute force in versions 1.8.71 up to, and including, 1.8.74. The wrong-attempt lockout added in 1.8.71 is ineffective. lwp_generate_token() resets the attempt counter every time a code is issued, and code requests have no rate limit. The lwp_ajax_register handler also counts failed attempts with a non-atomic read-then-write of user meta, so parallel requests can get past the limit. This makes it possible for unauthenticated attackers to make an unlimited number of guesses at a user's one-time login code, log in as that user (including administrators) and take over the account. As a side effect, the victim can be flooded with OTP messages.",
