Deeper analysis

CVE-2025-24636 is a Cross-Site Request Forgery (CSRF) vulnerability in the MachForm Shortcode WordPress plugin developed by Rick Laymance, which enables Stored XSS. The flaw affects the machform-shortcode plugin in all versions from n/a through 1.4.1 inclusive. It is associated with CWE-352 and carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network accessibility, low attack complexity, no required privileges, user interaction, changed scope, and low impacts across confidentiality, integrity, and availability.

An attacker can exploit this vulnerability remotely without authentication by tricking an authenticated user into performing an unintended action, such as submitting a malicious form via a crafted webpage or link. This CSRF leads to Stored XSS, where malicious scripts are persistently injected and executed in the context of the victim's browser with elevated cross-origin privileges due to the changed scope.

The Patchstack advisory provides detailed analysis of the vulnerability, including remediation guidance for the MachForm Shortcode plugin.
