Database data extraction via Activity Log col parameter
Published May 16, 2026 · Updated May 16, 2026
Blind SQL injection in FUEL CMS 1.4.13 allows remote authenticated users to extract database data through the Activity Log interface. The logs items endpoint incorporates the col parameter into a database query without neutralizing injected SQL, enabling time-delay inference. Access to the administrative Activity Log is required; crafted sleep expressions change response timing and disclose queried values without direct query output.
