WHAT IT DOES

What upload_library_file does on Freshdesk

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

RISK

Why upload_library_file is rated Medium

Uploading files creates new resources in SharePoint and modifies the state of the document library. This is reversible (files can be deleted), so it falls under Write rather than Destructive.

From the tool's definition Tool description states 'Upload a text file to a SharePoint document library', which is a create/write operation that adds new data to a storage system.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs upload_library_file safely

upload_library_file Rate-limited

upload_library_file stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
