Summary
ComfyUI before 0.30.0 fails to sanitize folder_name input in dataset save nodes, allowing attackers to write files to arbitrary paths outside the output directory. Attackers can load a crafted workflow that writes attacker-controlled content to arbitrary locations, enabling code execution through modified startup files or package initializers.
Risk Assessment
This can lead to remote code execution and full system compromise, as attackers can overwrite files executed at application startup.
Recommendation
Upgrade ComfyUI to version 0.30.0 or later. Restrict loading of untrusted workflows and monitor for file writes outside the output directory.
Other vulnerabilities in ComfyUI
See all- CVE-2026-68771Critical
ComfyUI v0.23.0 contains an unsafe deserialization vulnerability in the LoadTrainingDataset node. An unauthenticated attacker can upload a crafted pickle file via the POST /upload/image endpoint and trigger its deserialization via POST /prompt, leading to arbitrary Python code execution through torch.load.
- CVE-2026-56673High
ComfyUI prior to version 0.28.0 is vulnerable in folder_paths.get_annotated_filepath and exists_annotated_filepath. They join workflow-controlled filenames to a base directory without containment check, allowing an unauthenticated attacker to craft a POST /prompt request using LoadImage or similar nodes to probe arbitrary host paths and exfiltrate image-format files through /view.
- CVE-2026-56672High
ComfyUI prior to version 0.28.0 is vulnerable to stored cross-site scripting (XSS) in the GET /userdata/{file} endpoint. It serves user-controlled HTML and SVG files with extension-derived content types, allowing script execution in the ComfyUI origin and access to API tokens, settings, workflows, and authenticated-equivalent API calls.
- CVE-2026-56671High
ComfyUI prior to version 0.28.0 is vulnerable in the get_model_preview function in app/model_manager.py. It joins an unrestricted filename to a selected model directory without containment check, allowing an unauthenticated attacker to use traversal, absolute paths, or an unbounded path_index to read image-decodable files and enumerate host paths.
- CVE-2026-56670High
ComfyUI prior to version 0.28.0 is vulnerable to stored cross-site scripting (XSS) in the /view endpoint. It serves uploaded SVG files inline because image/svg+xml and related content types were not handled as dangerous, allowing script execution in the ComfyUI origin.
