CVE-2026-40833
Full vulnerability record from the local CVENow database.
Description
An low privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the dash.php files saveDashboardLayout function due to improper neutralization of special elements in a SQL INSERT command allowing for reading the whole database and inserting entries into a non critical table. This can result in a total loss of confidentiality and some loss of integrity.
