CVE-2026-119130 is fixed in rust-wasmtime on 1 platform by DEBIAN-CVE-2026-119130 (version 36.0.20+dfsg-1), released November 3, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Wasmtime before 36.0.18, 37.0.0 before 48.0.6, and 49.0.0 before 49.0.3 does not verify that set-path-with-query values in wasmtime-wasi-http are paths, so absolute-form URLs are written verbatim as the HTTP/1.1 request target while the connection uses the allowed authority. A malicious guest can supply an absolute URL that a forward proxy or gateway at that authority honors, reaching hosts disallowed by embedder filtering policies.
