langgenius dify XSS in Share Layout Components

Cross-site scripting in Dify 1.13.0 allows unauthenticated remote attackers to inject arbitrary client-side script via the redirect_url argument processed by the router.replace function in the Splash Layout component. Exploitation requires a single user interaction - the victim must follow a crafted link - but no account or prior access to the Dify instance is required. A public proof-of-concept exploit was disclosed on GitHub Gist on or around 2026-07-05; the vendor did not respond to the coordinated disclosure, and no confirmed patch is available at time of analysis.
