Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the validateKeyIdUrl function. An attacker can access internal resources, cloud metadata, or loopback services by sending a crafted Signature keyId to the public actor inbox route, bypassing network restrictions through the use of 6to4, NAT64, or IPv4-compatible IPv6 addresses.
