Vulnerability Title
Cross-Origin File Exfiltration via CORS Misconfiguration + Path Traversal in TinaCMS
Source: NVD (National Vulnerability Database)
Vulnerability Description
Tina is a headless content management system. Prior to 2.1.8 , the TinaCMS CLI dev server combines a permissive CORS configuration (Access-Control-Allow-Origin: *) with the path traversal vulnerability (previously reported) to enable a browser-based drive-by attack. A remote attacker can enumerate the filesystem, write arbitrary files, and delete arbitrary files on developer's machines by simply tricking them into visiting a malicious website while tinacms dev is running. This vulnerability is fixed in 2.1.8.
