Published: 2022-05-02 · updated 2026-06-17
Weakness: CWE-79

Description

The All In One WP Security & Firewall WordPress plugin before 4.4.11 does not validate, sanitise and escape the redirect_to parameter before using it to redirect user, either via a Location header, or meta url attribute, when the Rename Login Page is active, which could lead to an Arbitrary Redirect as well as Cross-Site Scripting issue. Exploitation of this issue requires the Login Page URL value to be known, which should be hard to guess, reducing the risk
