Real-World Exposure
october/october🐘october/systemReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.
Patches
Issue has been patched in Build 466 (v1.0.466) by applying the recommended patch from @jquery.
Workarounds
Apply https://github.com/octobercms/october/commit/5c7ba9fbe9f2b596b2f0e3436ee06b91b97e5892 to your installation manually if unable to upgrade to Build 466.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for october/october. 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 october/october to 1.0.466 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v73w-r9xg-7cr9 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-v73w-r9xg-7cr9 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-v73w-r9xg-7cr9. 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-v73w-r9xg-7cr9 in your dependencies?
O3 detects GHSA-v73w-r9xg-7cr9 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
