Description
NestJS Proxy is a NestJS module to decorate and proxy calls. Prior to version 0.7.0, the nestjs-proxy library did not have a way to control when Authorization headers should should be forwarded for specific backend services configured by the application developer. This could have resulted in sensitive information such as OAuth bearer access tokens being inadvertently exposed to such services that should not see them. A new feature has been introduced in the patched version of nestjs-proxy that allows application developers to opt out of forwarding the Authorization headers on a per service basis using the forwardToken config setting. Developers are advised to review the README for this library on Github or NPM for further details on how this configuration can be applied. This issue has been fixed in version 0.7.0 of @finastra/nestjs-proxy. Users of @ffdc/nestjs-proxy are advised that this package has been deprecated and is no longer being maintained or receiving updates. Such users should update their package.json file to use @finastra/nestjs-proxy instead.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2022-31069 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2022-31069 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2022-31069. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-31069 in your dependencies?
O3 detects CVE-2022-31069 across dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
