Security readout for executives and security teams
This MyBB issue lets someone with admin panel access abuse the Task Manager Add New Task area to include files. On modern PHP this can expose local files; on very old PHP it may allow remote file inclusion. It was reported as fixed in MyBB 1.8.15. Exposure is most likely on MyBB deployments not upgraded to 1.8.15 or later, especially where admin accounts are compromised, shared, or broadly accessible. The source bundle does not identify exact affected version ranges, hosting configurations, or default exposure conditions. Treat this as a priority for any internet-facing MyBB forum with multiple administrators or weak admin access controls. The admin-access requirement lowers broad internet risk, but file inclusion can expose sensitive files and may escalate impact if an admin account is compromised. Mitigation focus: Upgrade MyBB to 1.8.15 or later, following the official MyBB security release guidance.; Restrict admin panel access to trusted administrators and administrative networks.; Review admin accounts for compromise, shared use, and unnecessary privileges..
