CVE-2026-35050Public exploitNetwork attack vector

Authenticated code execution via extension-settings path overwrite

Published Apr 6, 2026 · Updated Apr 6, 2026

Path traversal in text-generation-webui before 4.1.1 allows remote authenticated users to execute code through the web interface. The extension-settings save handler trusts client-controlled folder, filename, and content fields, allowing a request to overwrite download-model.py in the application root. Access to the web UI with its high-privilege save capability is required; triggering a model download then runs the replacement file with the application's permissions.
