CVE-2024-52787Network attack vector

Arbitrary file write via unsanitized upload filename

Published Nov 25, 2024 · Updated Nov 27, 2024

Path traversal in vemonet libre-chat 0.0.6 and earlier allows remote attackers to write files outside the upload directory. The upload_documents method passes the supplied filename to os.path.join and opens the resulting path for writing without validating that it remains under documents_path. Network access to the unauthenticated upload interface is sufficient, and writes are limited to locations permitted to the server process.
