Vulnerability Title
Capgo - SSRF and Privilege Escalation via Path Traversal in Builder Upload Proxy
Source: CVE Program / CVE List V5
Vulnerability Description
Capgo before 12.128.2 contains a path traversal vulnerability in the builder upload proxy that allows authenticated users with build permissions to bypass upload restrictions. Attackers can append traversal sequences to the upload path, which are normalized by the WHATWG URL parser, enabling access to internal administrative endpoints with the privileged BUILDER_API_KEY header and resulting in server-side privilege escalation.
