CVE-2021-25102
Last modified
CVE-2021-25102 is a medium-severity vulnerability rated 4.7/10 on the CVSS scale. 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. EPSS estimates a 0.71% chance of exploitation in the next 30 days.
