Recurring patterns

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

Path Traversal: Gem installation paths and bindir resolution can be manipulated via directory traversal sequences if destination paths are not strictly canonicalized and verified against the gem's root prefix.

Path Traversal: Gem executables defined in specifications are vulnerable to directory traversal during pre-install validation if they are not constrained to strict basename checks.

Auth Bypass: Support for older package formats can result in silent bypasses of the configured security trust policy if verification logic does not explicitly forward the security policy to legacy handlers.
