CVE-2026-119130

The Wasmtime runtime (versions before 36.0.18 , 37.0.0 before 48.0.6 , and 49.0.0 before 49.0.3 ) is vulnerable to an HTTP Request Target Smuggling issue. The root cause is a failure to verify that set-path-with-query values in wasmtime-wasi-http are valid paths. Consequently, absolute-form URLs ...

CVE-2026-119130 Wasmtime before 36.0.18, 37.0.0 before 48.0.6, and 49.0.0 before 49.0.3 HTTP Request Target Smuggling

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...
