Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada openjsf marko, openjsf marko/runtime-tags. Skor CVSS 3.1 6.4 (Medium) menurut github.com.

Deskripsi (NVD)

Marko is a declarative, HTML-based language for building web apps. Prior to marko version 5.38.36 and prior to @marko/runtime-tags 6.0.164, when dynamic text is interpolated into a <script> or <style> tag the Marko runtime failed to prevent tag breakout when the closing tag used non-lowercase casing. An attacker able to place input inside a <script> or <style> block could break out of the tag with </SCRIPT>, </Style>, etc. and inject arbitrary HTML/JavaScript, resulting in cross-site scripting. This issue has been patched in marko version 5.38.36 and @marko/runtime-tags 6.0.164.
