[MAVEN:GHSA-XQPP-26PP-2365] XSS vulnerability in Jenkins Markdown Formatter Plugin

Severity Moderate

Affected Packages 1

Fixed Packages 1

CVEs 1

Jenkins Markdown Formatter Plugin 0.1.0 and earlier uses a Markdown library to parse Markdown that does not escape crafted link target URLs.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with the ability to edit any description rendered using the configured markup formatter.

Jenkins Markdown Formatter Plugin 0.2.0 uses a different Markdown library that is not affected by this problem.

Package	Affected Version
pkg:maven/io.jenkins.plugins/markdown-formatter	<= 0.1.0
