Cross-Site Scripting in express-cart
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.
express-cartnpmDescription
All versions of harp are vulnerable to Cross-Site Scripting. In the admin page it is possible to inject arbitrary JavaScript as a new product option, allowing attackers to execute arbitrary code. This is limited to the admin page and does not affect other pages.
Recommendation
No fix is currently available. Consider using an alternative module until a fix is made available.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for express-cart, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of express-cart has shipped for GHSA-9pr3-7449-977r 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-9pr3-7449-977r can be triaged on real exposure rather than presence alone.
Tailored to GHSA-9pr3-7449-977r. 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-9pr3-7449-977r in your dependencies?
O3 Security finds GHSA-9pr3-7449-977r across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
