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. Attackers can store malicious content that executes in the browser context when users view artifacts, leading to session compromise, credential theft, and arbitrary script execution.
