Description

A flaw was found in goose. An authorization bypass vulnerability allows tools to run without required user confirmation even when manual approval mode is selected. This occurs because read-only tool annotations from previous sessions are not properly cleared when switching approval modes. Consequently, an attacker could leverage prompt injection to execute tools automatically, bypassing the intended security controls.
