CVE intelligence and bounded remediation
CVE-2024-31462 — stable-diffusion-webui is a web interface for Stable Diffusion, implemented using Gradio library
stable-diffusion-webui is a web interface for Stable Diffusion, implemented using Gradio library. Stable-diffusion-webui 1.7.0 is vulnerable to a limited file write affecting Windows systems. The create_ui method (Backup/Restore tab) in modules/ui_extensions.py takes user input into the config_save_name variable on line 653. This user input is later used in the save_config_state method and used to create a file path on line 65, which is afterwards opened for writing on line 67, which leads to a limited file write exploitable on Windows systems. This issue may lead to limited file write. It allows for writing json files anywhere on the server where the web server has access.

Matched remediation archetype
Path traversal, unsafe upload, and file handling
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
- Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
- Review canonicalization and containment checks across supported operating systems and storage backends.
Remediate safely
- Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
- Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
- Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
