CVE-2025-51661 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A path Traversal vulnerability found in FileCodeBox v2.2 and earlier allows arbitrary file writes when application is configured to use local filesystem storage. SystemFileStorage.save_file method in core/storage.py uses filenames from user input without validation to construct save_path and save files. EPSS estimates a 0.46% chance of exploitation in the next 30 days.

Description

A path Traversal vulnerability found in FileCodeBox v2.2 and earlier allows arbitrary file writes when application is configured to use local filesystem storage. SystemFileStorage.save_file method in core/storage.py uses filenames from user input without validation to construct save_path and save files. This allows remote attackers to perform arbitrary file writes outside the intended directory by sending crafted POST requests with malicious traversal sequences to /share/file/ upload endpoint, which does not require any authorization.
