Administrator-context script execution via settings import

Published May 30, 2023 · Updated Jan 10, 2025

Cross-site scripting in Optimizing Matters Autoptimize before 3.1.7 allows remote authenticated users to run JavaScript in the admin panel. The Critical CSS settings importer accepts a crafted settings.json file inside a ZIP archive and stores an unescaped file value that renders as script. Administrator access to the importer is required, and the injected code runs in an administrator's browser even when unfiltered_html is disabled.
