A local attacker with filesystem access could copy and reuse the private key to impersonate a development TLS endpoint in an environment that trusts the certificate.\n\nThe generated certificate was also unnecessarily CA-capable and included broad key usages beyond its localhost HTTPS purpose. Its IPv6 loopback entry was encoded as a DNS name rather than an IP subject alternative name.\n\nThe remediation writes and repairs the cached PEM with owner-only permissions on supported platforms, generates a non-CA server-auth leaf certificate with constrained key usage, corrects the IPv6 loopback SAN, and bases cache expiry on content modification time so permission metadata changes cannot extend the certificate lifetime.
