CVE-2026-115893

The Wasmtime WebAssembly runtime is vulnerable to a sandbox escape on aarch64 engines using the default Cranelift backend. The issue occurs when processing a br_table instruction containing more than approximately 256,000 targets, causing an incorrect conditional branch target . This allows a use...

EUVD-2026-109188

Wasmtime is a runtime for WebAssembly. Prior to 36.0.19, 48.0.7, and 49.0.4, the Cranelift compiler backend on aarch64 can compile a Wasm brtable instruction with more than approximately 256,000 targets so that it has an incorrect conditional branch target. The branch can then jump to arbitrary...

CVE-2026-115889

The Wasmtime runtime is vulnerable to a numeric truncation error (CWE-197) and type confusion (CWE-843) in its Cranelift compiler backend prior to versions 36.0.19 and 43.0.0 . The root cause is a silent overflow occurring during the bit-packing of SSA value indices in release builds when process...

EUVD-2026-109186

Wasmtime is a runtime for WebAssembly. Prior to 36.0.19 and 43.0.0, the Cranelift compiler backend bit-packs SSA value indices in a way that can silently overflow in release builds when compiling a sufficiently large or specially crafted Wasm function with many SSA values. The overflow can make...
