Security debate: heap corruption inside WASM can still yield RCE without sandbox escape
MickeySteamboat · x · 2026-10-21
In a debate with MickeySteamboat and moyix, dcolascione argues that a WASM sandbox doesn't eliminate risk: there's still a heap inside WASM that can be corrupted and leveraged for RCE, letting attackers wreak plenty of havoc without escaping the sandbox. MickeySteamboat dismisses the point as "delusional," underscoring disagreement over WASM's security boundary.
