SCA: security update for @fastly/js-compute (GHSA-cmr8-5w4c-44v8)

high Tenable Cloud Security Plugin ID 413979

Description

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

 - The JS Compute Runtime for Fastly's Compute@Edge platform provides the environment JavaScript is executed
 in when using the Compute@Edge JavaScript SDK. In versions prior to 0.5.3, the `Math.random` and
 `crypto.getRandomValues` methods fail to use sufficiently random values. The initial value to seed the
 PRNG (pseudorandom number generator) is baked-in to the final WebAssembly module, making the sequence of
 random values for that specific WebAssembly module predictable. An attacker can use the fixed seed to
 predict random numbers generated by these functions and bypass cryptographic security controls, for
 example to disclose sensitive data encrypted by functions that use these generators. The problem has been
 patched in version 0.5.3. No known workarounds exist. (CVE-2022-39218)
