Deeper analysis
CVE-2024-50582 is a stored cross-site scripting vulnerability in JetBrains YouTrack versions prior to 2024.3.47707. It stems from improper HTML sanitization when processing markdown elements and is tracked under CWE-79. The issue carries a CVSS 3.1 base score of 4.6, reflecting network attack vector, low attack complexity, and low-privileged authenticated access with user-interaction requirements.
An authenticated attacker with low privileges can supply specially crafted markdown content that persists in the application. When another user views the affected content, the unsanitized markup executes in the victim's browser, allowing limited theft or manipulation of session data and page content within the YouTrack instance.
JetBrains has addressed the flaw in YouTrack 2024.3.47707; the vendor's security issues page lists the correction among resolved items and directs administrators to apply the updated release.
The associated EPSS score has remained steady at 0.2166 with no material upward trajectory after disclosure.
