Copyparty is a portable file server. Versions prior to 1.8.2 are subject to a path traversal vulnerability detected in the .cpr subfolder. The Path Traversal attack technique allows an attacker access to files, directories, and commands that reside outside the web document root directory. This issue has been addressed in commit 043e3c7d which has been included in release 1.8.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-37474
