CVE-2026-27204

Wasmtime is a runtime for WebAssembly. Prior to versions 24.0.6, 36.0.6, 4.0.04, 41.0.4, and 42.0.0, Wasmtime's implementation of WASI host interfaces are susceptible to guest-controlled resource exhaustion on the host. Wasmtime did not appropriately place limits on resource allocations requested...

CVE-2026-27195

Wasmtime is a runtime for WebAssembly. Starting with Wasmtime 39.0.0, the component-model-async feature became the default, which brought with it a new implementation of TypedFunc::callasync which made it capable of calling async-typed guest export functions. However, that implementation had a bu...

CVE-2026-27195

CVE-2026-27195 affects Wasmtime in versions where component-model-async is default (from 39.0.0). The bug causes a panic when a host embeds calls to wasmtime::component::[Typed]Func::call_async, drops the returned Future after polling, and then reuses the same component instance before the first ...

Wasmtime WASI implementations are vulnerable to guest-controlled resource exhaustion

Impact Wasmtime's implementation of WASI host interfaces are susceptible to guest-controlled resource exhaustion on the host. Wasmtime did not appropriately place limits on resource allocations requested by the guests. This serves as a Denial of Service vector where a guest can induce a range of...

Wasmtime is vulnerable to panic when dropping a `[Typed]Func::call_async` future

The affected versions of Wasmtime can panic if the host embedder drops the future returned by wasmtime::component::TypedFunc::callasync before it resolves. Details Starting with Wasmtime 39.0.0, the component-model-async feature became the default, which brought with it a new implementation of...

Improper Handling of Case Sensitivity

Overview Affected versions of this package are vulnerable to Improper Handling of Case Sensitivity in the host request matcher when the host list contains more than 100 entries. An attacker can gain unauthorized access to protected routes and sensitive endpoints by altering the case of the Host...

Caddy: MatchHost becomes case-sensitive for large host lists (>100), enabling host-based route/auth bypass

Summary Caddy's HTTP host request matcher is documented as case-insensitive, but when configured with a large host list 100 entries it becomes case-sensitive due to an optimized matching path. An attacker can bypass host-based routing and any access controls attached to that route by changing the...
