CVE-2023-25485Network attack vector

Stored script execution via unescaped administrator input

Published Apr 25, 2023 · Updated Apr 28, 2026

Stored XSS in Bernhard Kux Get Use APIs – JSON Content Importer 1.3.15 and earlier allows remote authenticated users to inject scripts. The plugin insufficiently sanitizes stored administrator-supplied input and fails to escape it when generating a page; public sources do not identify the affected field or function. Administrator access is required to store the payload, and another user must load the affected page for script execution in that user's browser.
