CVE-2026-7623 is a stored cross-site scripting vulnerability in the SureForms – Contact Form Builder, AI Forms, Payment Form, Survey & Quiz WordPress plugin by brainstormforce. The issue exists in the 'headingWrapper' parameter, allowing authenticated users with contributor-level privileges or above to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages. The vulnerability is due to improper neutralization of input during web page generation (CWE-79). It affects all versions up to and including 2.8.1. The CVSS 3.1 base score is 6.4, indicating a medium severity level.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable parameter. This can lead to unauthorized script execution in the context of users viewing those pages, potentially resulting in data theft, session hijacking, or other client-side attacks. The vulnerability does not affect availability but impacts confidentiality and integrity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the 'headingWrapper' parameter if possible. Monitor for updates from brainstormforce regarding patches or official mitigations.
