Description OSIDB Bzimport 2025-09-08 21:33:30 UTC 
An unauthenticated client can control which host:port the proxy connects to by choosing a realm whose DNS publishes SRV records, leading to unbounded SRV auto discovery being used to make server-side connections across a trust boundary (including localhost/RFC1918) with no port/address policy and no validation of upstream responses, resulting in SSRF (CWE-918), data exfiltration, and origin-cloaked egress.
