Real-World Exposure
de.ipb-halle:molecularfacesReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The viewer plugin implementation of <mol:molecule> renders molfile data directly inside a <script> tag without any escaping. Arbitrary JavaScript code can thus be executed in the client browser via crafted molfiles.
Patches
Patched in v0.3.0: Molfile data is now rendered as value of a hidden <input> tag and escaped via JSF's mechanisms.
Workarounds
No workaround available.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for de.ipb-halle:molecularfaces. 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 de.ipb-halle:molecularfaces to 0.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2pwh-52h7-7j84 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-2pwh-52h7-7j84 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-2pwh-52h7-7j84. 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-2pwh-52h7-7j84 in your dependencies?
O3 detects GHSA-2pwh-52h7-7j84 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
