CVE-2024-50580Network attack vector

Browser script execution via unsafe markdown rendering

Published Oct 28, 2024 · Updated Oct 28, 2024

Cross-site scripting in JetBrains YouTrack before 2024.3.47707 allows remote authenticated users to run script in another user's browser. Markdown parsing and a custom rendering rule fail to neutralize attacker-controlled content before it is rendered as a web page. A low-privileged account must supply the content and another user must view it; successful exploitation executes script in the viewing user's application context.
