Description

Two XSS vulnerabilities were fixed in message list and view in the Hupa Webmail application from the Apache James project. An attacker could send a carefully crafted email to a user of Hupa which would trigger a XSS when the email was opened or when a list of messages were viewed. This issue was addressed in Hupa 0.0.3.

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.apache.james.hupa:hupa-parent, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.james.hupa:hupa-parent to 0.0.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2012-3536 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.
