WHAT IT DOES

What php_set_max_size does on Aapanel

AI agents use php_set_max_size to create or update resources in Aapanel, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aapanel environment.

RISK

Why php_set_max_size is rated Medium

This tool modifies PHP configuration by changing the max upload size parameter. This is a reversible Write operation as the setting can be changed back, but the severity is high because misconfiguration could impact server functionality, potentially cause denial of service if set to extreme values, or enable/disable file upload capabilities.

From the tool's definition Tool name 'php_set_max_size' and description 'Set PHP max upload size for a version' indicate modification of PHP configuration settings. 'Set' is an explicit write operation that alters server configuration.
