Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada authcrunch caddy-security. Skor CVSS 3.1 6.1 (Medium) menurut snyk.io.

Deskripsi (NVD)

All versions of the package github.com/greenpau/caddy-security are vulnerable to Cross-site Scripting (XSS) via the Referer header, due to improper input sanitization. Although the Referer header is sanitized by escaping some characters that can allow XSS (e.g., [&], [<], [>], ["], [']), it does not account for the attack based on the JavaScript URL scheme (e.g., javascript:alert(document.domain)// payload). Exploiting this vulnerability may not be trivial, but it could lead to the execution of malicious scripts in the context of the target user’s browser, compromising user sessions.
