How urgent is this, really
GHSA-mhpp-875w-9cpv by exploitation likelihood (EPSS) against impact (CVSS). Outside the shaded patch-first corner.
Where this sits among everything scored
Of 397,508 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Counts from FIRST.org, log-scaled.
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.
jquerynpmDescription
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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
