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

Deskripsi (NVD)

Versions of the package github.com/yuin/goldmark/renderer/html before 1.7.17 are vulnerable to Cross-site Scripting (XSS) due to improper ordering of URL validation and normalization. The renderer validates link destinations using a prefix-based check (IsDangerousURL) before resolving HTML entities. This allows an attacker to bypass protocol filtering by encoding dangerous schemes using HTML5 named character references. For example, a payload such as javascript:alert(1) is not recognized as dangerous during validation, leading to arbitrary script execution in the context of applications that render the URL.
