Description

Pimcore is an open source data and experience management platform. Versions prior to 10.5.19 have an unsecured tooltip field in DataObject class definition. This vulnerability has the potential to steal a user's cookie and gain unauthorized access to that user's account through the stolen cookie or redirect users to other malicious sites. Users should upgrade to version 10.5.19 or, as a workaround, apply the patch manually.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update pimcore/pimcore to 10.5.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-28429 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.
