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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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.
