JavaScript execution via malicious molfiles (XSS)
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.
