CVE-2026-57149Network attack vectorHinoki check available

Authenticated code execution via TALES expression injection

Published Sep 22, 2026 · Updated Sep 22, 2026

Code injection in Plone plone.app.portlets before 5.0.8, 6.0.4, and 7.0.2 allows remote authenticated users to execute server code. The Classic portlet passes user-supplied template or macro values to the TAL path() helper as complete TALES expressions, permitting python: expressions or fallback chains. Exploitation requires permission to add or edit Classic portlets; the default role map grants regular users that permission on personal dashboards.
