WHAT IT DOES

RISK

Why browser_cookie_set is rated Medium

Setting cookies is a reversible write operation that modifies browser state. It could be misused to inject malicious cookies, impersonate users, or manipulate site behavior, but lacks the irreversibility of destructive operations or the financial impact of transactions. High severity due to potential authentication/session hijacking implications in an automated browser context.

From the tool's definition Tool name 'browser_cookie_set' indicates cookie creation or modification. No description provided, but the context of browser automation and sibling tools like 'browser_auth_save' and 'browser_attr_set' establish this as a data modification operation.
