WHAT IT DOES

RISK

Why servicenow_attachment is rated Medium

Attachment operations on ServiceNow are Write-category actions because they create or add new attachments/files to records. This is reversible (attachments can be removed) and does not delete data. Severity is medium due to potential for uploading malicious files or attaching sensitive content to records unintentionally, affecting data integrity and compliance.

From the tool's definition Tool name 'servicenow_attachment' suggests file attachment operations (create, upload, associate). Description is empty, limiting certainty. ServiceNow attachment operations typically involve creating or modifying attachments linked to records.
