SQL Injection in Filerun
CVE-2026-73698
FileRun before 2026.3.0 contains a SQL injection vulnerability that allows delegated or simple administrators to execute arbitrary SQL by submitting the description parameter as an array, causing the getValuesString() method in DB/DP.php to interpolate raw array values directly into an INSERT statement without parameterization. Because the underlying PDO connection uses emulated prepared statements enabling stacked queries, attackers can manipulate the df_users_permissions table to escalate a delegated administrator account to superuser privileges, and may additionally achieve code execution via unsanitized path values passed to require_once in the logs listing component.
