@ai-sdk/provider-utils is vulnerable to Server-Side Request Forgery (SSRF)
74
High Risk
This Affects:
@ai-sdk/provider-utilsTL;DR
The downloadBlob helper in @ai-sdk/provider-utils fetches a caller-supplied URL without validating its protocol, hostname, or destination IP. The fix introduces a shared validateDownloadUrl utility that rejects non-HTTP(S) schemes, loopback, link-local, and private IPv4 and IPv6 ranges before any network request is made. The fix also validates the URL after redirects.
