Deeper analysis
CVE-2023-25346 is a reflected cross-site scripting vulnerability affecting ChurchCRM version 4.5.3. The flaw resides in the handling of the id parameter within the /churchcrm/v2/family/not-found endpoint, which fails to properly sanitize user-supplied input and permits injection of arbitrary web scripts or HTML.
Remote attackers can exploit the issue without authentication by crafting a malicious link that includes the payload in the id parameter and tricking a victim into clicking it. Successful exploitation allows the attacker to execute scripts in the victim's browser context, potentially resulting in limited data exposure or unauthorized actions within the ChurchCRM application due to the changed scope.
The provided references point to public disclosure materials and the ChurchCRM repository but contain no explicit details on patches or mitigation steps. The associated EPSS score has remained flat at 0.1235 with no material increase observed after disclosure.
