## Summary

The Two Factor Authentication WordPress plugin and the All-In-One Security (AIOS) WordPress plugin are affected by this vulnerability. An attacker who already knows a victim's password could use their own two-factor-enabled account to pass the victim's second-factor check and gain access to the victim's logged-in session.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Unknown Two Factor Authentication: fixed in 1.17.0
- Unknown All-In-One Security (AIOS): fixed in 5.5.0

## Description

The Two Factor Authentication WordPress plugin before 1.17.0, All-In-One Security (AIOS) WordPress plugin before 5.5.0 do not bind the account whose two-factor code is verified to the account being authenticated, allowing an attacker who knows a victim's password and holds their own two-factor-enabled account to satisfy the victim's second-factor check with their own code and obtain the victim's session.
