dbcve analysis
How this class of weakness works · CWE-732

A sensitive file, directory, or resource is created with permissions more open than it needs, so unintended users can read or modify it. Attackers look for exactly these loose defaults. Remediation is assigning the minimum permissions required and verifying them at install time and at runtime.
