Threats tagged 'ghsa-87fv-vqqr-m4jr'

SeaweedFS versions prior to 4.24 contain an unauthenticated Server-Side Request Forgery (SSRF) vulnerability in the VolumeServer.FetchAndWriteNeedle RPC. This RPC fetches a caller-supplied remote endpoint and writes the response into a needle without authentication or target validation, allowing attackers with network access to the volume server's gRPC port to coerce requests to arbitrary internal or external hosts and read the responses. This includes sensitive cloud metadata endpoints that can disclose instance metadata and IAM credentials. The vulnerability is fixed in version 4.24 by requiring admin authorization and blocking requests to loopback, link-local, RFC 1918, and cloud metadata IPs. Workarounds include restricting access to the gRPC port and enabling mTLS.
