CVE-2026-82288Public exploitNetwork attack vector

Credential disclosure via unfiltered command flags

Published Aug 28, 2026 · Updated Aug 28, 2026

Credential disclosure in AUTOMATIC1111 Stable Diffusion WebUI 1.10.1 and earlier allows remote attackers to read configured credentials. The /sdapi/v1/cmd-flags handler returns the complete parsed command-line option namespace without filtering gradio_auth or api_auth values. Exposure requires the REST API to be enabled without api_auth and reachable over a network; the disclosed credentials permit access to the protected interface.
