CVE-2026-4510 Details
Description
A weakness has been identified in PbootCMS up to 3.2.12. This impacts the function alert_location of the file apps/home/controller/MemberController.php of the component Parameter Handler. This manipulation of the argument backurl causes cross site scripting. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks.
A vulnerability allowing open redirection and reflected cross-site scripting (XSS) has been identified in PbootCMS versions prior to 3.2.12. The issue arises in the MemberController.php file, specifically within the alert_location function of the Parameter Handler component. The vulnerability is triggered by manipulating the backurl parameter, which is used as a redirect target after login. This parameter is also inserted into the JavaScript output without proper encoding, enabling remote exploitation.
To address this vulnerability, redirect targets should be restricted to relative internal paths or a strict allowlist. Additionally, context-aware output encoding should be applied for JavaScript outputs, and server-side redirects should be preferred over inline script generation.
