@sefiros1 Thanks for opening the issue.

semver@6 is used in this module elastic-apm-http-client and in elastic-apm-node (the module for this this repo exists):

elastic-apm-node@3.47.0 /Users/trentm/el/apm-agent-nodejs
├─┬ elastic-apm-http-client@11.4.0
│ └── semver@6.3.0 deduped
└── semver@6.3.0

The vuln is a ReDoS vuln when untrusted input is given to semver.Range, also indirectly used by semver.satisfies(ver, range). The latter is used in many places in this code. However, in none of them is untrusted input given to the "range" argument. I suppose one arguable usage is this:

lib/opentelemetry-metrics/index.js
18:const isOTelMetricsFeatSupported = semver.satisfies(process.version, _supportRange)

However, that _supportsRange is from "node_modules/@opentelemetry/sdk-metrics/package.json". If that has been compromised in the install of this package, then the security game is up already. In conclusion: I don't think this package is affected by this vulnerability in semver.

Normally, one would just update to a fixed version of semver and move on. However, there isn't one that we can use. Currently per npm/node-semver#564 (comment) there is only a released fix for semver@7 and no current plans to backport.

We cannot use semver@7 because it's minimum supported Node.js version is v10. This package, elastic-apm-node@3, currently supports back to Node.js v8.6. (Note that we are currently planning a v4 major version bump that will drop support for Node.js v8. For that version we will upgrade our semver dependency.

---

I realize that this means we will fail npm audit until elastic-apm-node@4 is released (there is no current release date plan for that). Hopefully that is not too disruptive for users.
