Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The wasmtime-wasi-http crate is vulnerable in versions before 36.0.18, from 37.0.0 before 48.0.6, and from 49.0.0 before 49.0.3. The source gives few details beyond the title, which indicates that a guest can send absolute-form HTTP requests to hosts other than the intended one. Upgrade to 36.0.18, 48.0.6, 49.0.3, or a later patched release.
