A bug report and related fix attempts address a gap in SSRF protection where IPv4-translated IPv6 addresses (::ffff:0:x.x.x.x) are not evaluated by their embedded IPv4 component, allowing bypass of configured restrictions. The members cover the vulnerability report and at least two fix iterations targeting the same classification logic.
