GHSA-mhpp-875w-9cpv
HIGHDenial of Service in jquery
Blast Radius
org.webjars.npm:jquery📦jquery.NETjQuery💎jquery-railsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven, npm, NuGet packages — download data is not available via public APIs for these ecosystems.
Description
Affected versions of jquery use a lowercasing logic on attribute names. When given a boolean attribute with a name that contains uppercase characters, jquery enters into an infinite recursion loop, exceeding the call stack limit, and resulting in a denial of service condition.
Recommendation
Update to version 3.0.0 or later.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.webjars.npm:jquery. 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.
Fix
Update org.webjars.npm:jquery to 3.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mhpp-875w-9cpv is resolved across your whole dependency graph.
Workarounds
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-mhpp-875w-9cpv 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-mhpp-875w-9cpv. 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-mhpp-875w-9cpv in your dependencies?
O3 detects GHSA-mhpp-875w-9cpv across Maven, npm, NuGet dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
