Prior to commit 00b7c3c, the endpoint accepts user-supplied files[].url, performs a server-side fetch using \"requests.get(url, allow_redirects=True)\". The fetched bytes are then returned inside a ZIP response. This enables SSRF with response exfiltration. Redirect-following is enabled, and there is no timeout in the vulnerable fetch path.
