CVE-2025-0981: churchcrm Auth Bypass — Exploit

Description

A vulnerability exists in ChurchCRM 5.13.0 and prior that allows an attacker to hijack a user's session by exploiting a Stored Cross Site Scripting (XSS) vulnerability in the Group Editor page. This allows admin users to inject malicious JavaScript in the description field, which captures the session cookie of authenticated users. The cookie can then be sent to an external server, enabling session hijacking. It can also lead to information disclosure, as exposed session cookies can be used to impersonate users and gain unauthorised access to sensitive information.
