Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Incomplete validation allowed disallowed 'prompts/get' and 'resources/read' requests to bypass authorization checks and reach the underlying MCP server. Attackers could exploit this to retrieve restricted resources or prompts.

Auth Bypass: Case-sensitivity mismatches in pattern processing allowed attackers to bypass security restrictions by using mixed-case entity types that eluded exact-match filters.
