Medium severity, CVSS 5.4. EPSS: 0.3% chance of exploitation in the next 30 days.

ByteDance DeerFlow versions prior to commit 5dbb362 contain a stored cross-site scripting vulnerability in the artifacts API that allows attackers to execute arbitrary scripts by uploading malicious HTML or script content as artifacts.
