chore(ci): ignore RUSTSEC-2026-0189 (rmcp HTTP transport not used) - #41

Conversation
The advisory is a DNS-rebinding flaw in rmcp's Streamable HTTP server transport (missing Host-header validation). sudo-proxy is not affected: the advisory explicitly excludes non-HTTP transports, and this crate enables only rmcp's `transport-io` feature and serves the MCP server over stdio (src/bin/sudo-proxy-mcp.rs). The vulnerable HTTP transport is not compiled in. Document the rationale and ignore the ID in both advisory gates: deny.toml [advisories].ignore and the `cargo audit` step.

…triage (#42) Changelog: add a 2026-09-07 entry (release/hygiene, not a ladder rung) covering the publication of io.github.tarides/sudo-proxy 1.0.0 to the official MCP Registry once cargo support shipped upstream, the removal of the obsolete registry-watch tripwire (PR #40), and the RUSTSEC-2026-0189 not-applicable triage and suppression (PR #41). Backlog: capture one contingent follow-up — re-evaluate the RUSTSEC-2026-0189 ignore if an HTTP transport is ever added. The current assurance-ladder task is unchanged.

Cargo.tomlenables only rmcp'stransport-iofeature — the HTTP/streamable-http server transport is not compiled in.McpProxy::new().serve(stdio())(src/bin/sudo-proxy-mcp.rs). There is no HTTP listener for a rebinding attack to reach.This suppresses the false positive in both advisory gates, with the rationale documented inline:
