Authenticated browser script execution via crafted entry

Published Oct 2, 2024 · Updated Mar 14, 2025

Cross-site scripting in FlatPress 1.3 allows remote authenticated users to execute JavaScript in a victim's browser via Add New Entry. The Add New Entry administration feature accepts crafted content that reaches browser rendering without sufficient neutralization; public sources do not identify the responsible function or parameter. A valid FlatPress account and victim interaction are required, and successful exploitation can read browser-accessible data or alter displayed content.
