Real-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 are vulnerable to cross-site scripting. This occurs because the main jquery function uses a regular expression to differentiate between HTML and selectors, but does not properly anchor the regular expression. The result is that jquery may interpret HTML as selectors when given certain inputs, allowing for client side code execution.

Proof of Concept

$("#log").html(
    $("element[attribute='<img src=\"x\" onerror=\"alert(1)\" />']").html()
);

Recommendation

Update to version 1.9.0 or later.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    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.

  2. Fix

    Update org.webjars.npm:jquery to 1.9.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2pqj-h3vj-pqgw is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-2pqj-h3vj-pqgw 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-2pqj-h3vj-pqgw. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Frequently Asked Questions

Affected versions of `jquery` are vulnerable to cross-site scripting. This occurs because the main `jquery` function uses a regular expression to differentiate between HTML and selectors, but does not properly anchor the regular expression. The result is that `jquery` may interpret HTML as selectors when given certain inputs, allowing for client side code execution. ## Proof of Concept ``` $("#log").html( $("element[attribute='<img src=\"x\" onerror=\"alert(1)\" />']").html() ); ``` ## Recommendation Update to version 1.9.0 or later.
