Authenticated command execution with higher privileges
Published May 13, 2026 · Updated May 13, 2026
Privilege-management flaw in F5 BIG-IP scripted monitors allows remote authenticated users to execute commands with higher privileges. F5 identifies the scripted-monitor subsystem but has not disclosed the vulnerable function or how monitor data reaches the higher-privilege command path. Exploitation requires the Resource Administrator or Administrator role; appliance mode permits a security-boundary crossing, while the reported impact is limited to confidentiality and integrity.
