Vulnerability from github – Published: 2022-05-24 19:03 – Updated: 2023-10-27 14:40

Summary

XSS vulnerability in Jenkins Markdown Formatter Plugin

Details

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.

Severity

5.4 (Medium)
