AnalysisAI
Server-side request forgery in Yuxi-Know versions up to 0.4.0 allows high-privileged authenticated attackers to manipulate the health_url parameter in the OtherEmbedding.aencode function, causing the server to make unauthorized requests to internal or external services. The vendor has confirmed the vulnerability and disabled URL parsing as a mitigation. Public exploit code exists but no active exploitation has been reported.
