CVE-2023-30590 — The generateKeys() API function returned from crypto

The generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or outdated) keys, that is, it only generates a private key if none has been set yet, but the function is also needed to compute the corresponding public key after calling setPrivat

01What is this vulnerability?

The generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or outdated) keys, that is, it only generates a private key if none has been set yet, but the function is also needed to compute the corresponding public key after calling setPrivateKey().
