The built-in stream: resource type let a template bypass Security stream restrictions. BasePlugin::load() matches the 'stream' sysplugin before the stream_get_wrappers()/isTrustedStream() check, so a resource such as stream:php://filter/read=convert.base64-encode/resource=/path was opened by StreamPlugin::getContent() via fopen() on the nested php:// wrapper without ever validating it. This bypassed Security::$streams (including Security::$streams = null) and allowed reading arbitrary local files. Parse the wrapper scheme from the resolved path in StreamPlugin::getContent() and validate it with Security::isTrustedStream() before fopen(), giving the stream: resource the same check the direct wrapper path already receives. Adds regression tests covering the disabled-streams bypass, the not-on-allowlist case, and a positive test that an explicitly allowed wrapper still works.
