What is GHSA-f8pq-3926-8gx5?
GHSA-f8pq-3926-8gx5 is a code injection vulnerability in @opentelemetry/instrumentation, published on 9 Aug 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Impact
The import-in-the-middle loader used by @opentelemetry/instrumentation works by generating a wrapper module on the fly. The wrapper uses the module specifier to load the original module and add some wrapping code. It allows for remote code execution in cases where an application passes user-supplied input directly to an import() function.
Patches
This vulnerability has been patched in @opentelemetry/instrumentation version 0.41.2
Workarounds
- Do not pass any user-supplied input to
import(). Instead, verify it against a set of allowed values. - If using
@opentelemetry/instrumentationwith support for EcmaScript Modules is not needed, ensure that none of the following options are set (either via command-line or theNODE_OPTIONSenvironment variable):
--experimental-loader=@opentelemetry/instrumentation/hook.mjs
--experimental-loader @opentelemetry/instrumentation/hook.mjs
--loader=import-in-the-middle/hook.mjs
--loader import-in-the-middle/hook.mjs
