Unauthenticated service hang via oversized upload filename
Published Mar 20, 2025 · Updated Mar 20, 2025
Denial of service in Stable Diffusion WebUI 1.10.0 allows remote attackers to hang the server via a crafted file upload request. The file-upload handler accepts an excessively large multipart form-data filename and consumes enough server resources to make the interface unresponsive. No authentication or user interaction is required, and the demonstrated consequence is a service hang that prevents legitimate access.
