Real-World Exposure

1 pkg affected
☕de.ipb-halle:molecularfaces

Real-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 dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for de.ipb-halle:molecularfaces, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. 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.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
