CVE-2023-39333

Name of the Vulnerable Software and Affected Versions Node.js versions prior to the fixed version

Description 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 issue affects users of any active release line of Node.js, but the vulnerable feature is only available if Node.js is started with the --experimental-wasm-modules command line option.

Recommendations As a temporary workaround, consider disabling the --experimental-wasm-modules command line option until a patch is available. Restrict access to the WebAssembly module to minimize the risk of exploitation. Avoid using the vulnerable feature until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
