GHSA-2PMR-289P-44R3 Gotenberg's DNS rebinding bypasses SSRF validation on Chromium URL conversion routes

Summary FilterOutboundURL resolves the hostname, checks the resolved IPs against the private-address deny-list, and returns only the error. It discards the resolved addresses. Chromium later performs its own DNS resolution when it navigates to the URL. An attacker who controls DNS for a hostname...
