SCA: security update for sm-crypto (GHSA-vh45-f885-3848)

critical Tenable Self-Hosted Container Security Plugin ID 445944

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - sm-crypto provides JavaScript implementations of the Chinese cryptographic algorithms SM2, SM3, and SM4.
 Prior to 0.5.0, the default no-argument sm2.generateKeyPairHex() path in Node.js uses the module-wide
 SecureRandom instance in src/sm2/utils.js, supplied by [email protected], which seeds an ARC4 stream from
 Math.random() and new Date().getTime() because window.crypto.getRandomValues is unavailable even though
 globalThis.crypto exists. An attacker who can observe the process's Math.random() outputs and estimate the
 key-generation time can reconstruct the seed, recover generated SM2 private keys, and predict signing
 ephemeral scalars used to forge signatures. This issue is fixed in version 0.5.0. (CVE-2026-73567)

Solution

Update the sm-crypto library and its related packages to version 0.5.0 or later.
