CVE-2024-37166Network attack vector

Cross-site scripting via incomplete template-context escaping

Published Jun 10, 2024 · Updated Aug 2, 2024

XSS in gurgunday ghtml before 2.0.0 allows remote authenticated users to run JavaScript through unsafe template expressions. The html tag escapes basic HTML metacharacters but does not contextually encode unquoted attribute values or restrict attacker-controlled href schemes; before 2.0.0 it also leaves backticks unescaped. Exploitation requires an application to place attacker-controlled data in one of these contexts and a user to render the resulting markup, exposing browser-context data and content.
