CVE-2026-34988

Wasmtime is a runtime for WebAssembly. From 28.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's implementation of its pooling allocator contains a bug where in certain configurations the contents of linear memory can be leaked from one instance to the next. The implementation of resetting the...

CVE-2026-34983

Wasmtime is a runtime for WebAssembly. In 43.0.0, cloning a wasmtime::Linker is unsound and can result in use-after-free bugs. This bug is not controllable by guest Wasm programs. It can only be triggered by a specific sequence of embedder API calls made by the host. Specifically, the following...

CVE-2026-34944 Wasmtime segfault or unused out-of-sandbox load with `f64x2.splat` operator on x86-64

Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, On x86-64 platforms with SSE3 disabled Wasmtime's compilation of the f64x2.splat WebAssembly instruction with Cranelift may load 8 more bytes than is necessary. When signals-based-traps are disabled this can resul...

CVE-2026-34942 Wasmtime panics when transcoding misaligned utf-16 strings

Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime's implementation of transcoding strings into the Component Model's utf16 or latin1+utf16 encodings improperly verified the alignment of reallocated strings. This meant that unaligned pointers could be...

CVE-2026-34941

Wasmtime (WebAssembly runtime) contains a heap OOB read during transcoding of UTF-16 to the latin1+utf16 component-model encoding. The bug stems from validating the input length by code units instead of by byte length, causing reads beyond the WebAssembly linear memory during bounds checking. In ...

GHSA-4F8G-77MW-3RXC OpenClaw: Gateway plugin HTTP `auth: gateway` widens identity-bearing `operator.read` requests into runtime `operator.write`

Impact Gateway plugin HTTP auth: gateway widens identity-bearing operator.read requests into runtime operator.write. Plugin HTTP routes using gateway auth could receive runtime write scopes even when the upstream trusted-proxy request only declared read. OpenClaw is a user-controlled local...

Node.js: Node.js: Denial of Service due to crafted HTTP `__proto__` header

A flaw was found in Node.js. A remote attacker can exploit this vulnerability by sending a specially crafted HTTP request that includes a header named proto. When a Node.js application processes this request and attempts to access distinct headers, it encounters an unhandled error, leading to an...
