GHSA-w6xj-45gv-fw35
GHSA-w6xj-45gv-fw35 is a security vulnerability in stream-combine. O3 Security confirms whether GHSA-w6xj-45gv-fw35 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Malicious Package in stream-combine
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
stream-combinenpmDescription
Version 2.0.2 of stream-combine has malicious code design to steal credentials and credit card information. The code searches all form elements for passwords, credit card numbers and CVC codes. It then uploads the information to a remote server using HTML links embedded in the page or form actions. If your application has Content Security Policy set you are not affected by this issue.
Recommendation
This package is not available on the npm Registry anymore. If you used this module and your application processed credentials or credit card information, it is possible that information was stolen.
Users may consider downgrading to version 2.0.1

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for stream-combine. 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 stream-combine has shipped for GHSA-w6xj-45gv-fw35 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 GHSA-w6xj-45gv-fw35 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 GHSA-w6xj-45gv-fw35. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-w6xj-45gv-fw35 in your dependencies?
O3 detects GHSA-w6xj-45gv-fw35 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
