ChurchCRM v4.5.4 – Reflected XSS via Image (Authenticated)

The ChurchCRM v4.5.4 software is vulnerable to a reflected cross-site scripting (XSS) attack. An authenticated attacker can upload a specially crafted image file containing XSS payload and exploit the vulnerability by tricking a user into viewing the image, resulting in the execution of malicious script code within the user's browser.

Mitigation:

To mitigate this vulnerability, it is recommended to sanitize user input and validate image files before allowing them to be uploaded. Implementing a strict content security policy (CSP) can also help prevent XSS attacks.
