Vulnerability Title
4ga Boards: Import Path Traversal Leads to Arbitrary File Read
Source: CVE Program / CVE List V5
Vulnerability Description
4ga Boards is a boards system for realtime project management. Prior to 3.3.5, a path traversal vulnerability allows an authenticated user with board import privileges to make the server ingest arbitrary host files as board attachments during BOARDS archive import. Once imported, the file can be downloaded through the normal application interface, resulting in unauthorized local file disclosure. This vulnerability is fixed in 3.3.5.
