CVE intelligence and bounded remediation
CVE-2024-5278 — Gaizhenbiao Chuanhuchatgpt security vulnerability
gaizhenbiao/chuanhuchatgpt is vulnerable to an unrestricted file upload vulnerability due to insufficient validation of uploaded file types in its `/upload` endpoint. Specifically, the `handle_file_upload` function does not sanitize or validate the file extension or content type of uploaded files, allowing attackers to upload files with arbitrary extensions, including HTML files containing XSS payloads and Python files. This vulnerability, present in the latest version as of 20240310, could lead to stored XSS attacks and potentially result in remote code execution (RCE) on the server hosting the application.

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.
