CVE-2026-115379

Wasmtime versions 47.0.0 before 48.0.4 and 49.0.0 before 49.0.2 are vulnerable to a missing GC rooting flaw during the compilation of Wasm modules. The root cause is that references remain live across an unrooted try_call , allowing an attacker to provide Wasm modules where a callee triggers garb...

Wasmtime 47.0.0 before 48.0.4 and 49.0.0 before 49.0.2 contains a missing GC rooting vulnerability that leaves references live across trycall unrooted when compiling Wasm modules. Attackers can supply Wasm modules whose callee triggers garbage collection, leaving stale or dangling references that...

Remote Code Execution (RCE)

Yoke is vulnerable to Remote Code Execution RCE. The vulnerability is due to insufficient validation of the overrides.yoke.cd/flight annotation in the Air Traffic Controller ATC component, where attacker-controlled URLs are used to download and execute arbitrary WASM modules. This allows users wi...

UBUNTU-CVE-2023-39333

Maliciously crafted export names in an imported WebAssembly module can inject JavaScript code. The injected code may be able to access data and functions that the WebAssembly module itself does not have access to, similar to as if the WebAssembly module was a JavaScript module. This vulnerability...

GO-2022-0247 Buffer overflow in WASM modules in misc/wasm and cmd/link

When invoking functions from WASM modules, built using GOARCH=wasm GOOS=js, passing very large arguments can cause portions of the module to be overwritten with data from the arguments due to a buffer overflow error. If using wasmexec.js to execute WASM modules, users will need to replace their...
