GHSA-9pr3-7449-977r
GHSA-9pr3-7449-977r is a remote code execution vulnerability in express-cart. O3 Security confirms whether GHSA-9pr3-7449-977r is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Cross-Site Scripting in express-cart
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
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. 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 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 pinpoints whether GHSA-9pr3-7449-977r 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-9pr3-7449-977r. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
