#14772 00c579a Thanks @matthewp! - Improves the security of Server Islands slots by encrypting them before transmission to the browser, matching the security model used for props. This improves the integrity of slot content and prevents injection attacks, even when component templates don't explicitly support slots.
Slots continue to work as expected for normal usage—this change has no breaking changes for legitimate requests.
#14771 6f80081 Thanks @matthewp! - Fix middleware pathname matching by normalizing URL-encoded paths
Middleware now receives normalized pathname values, ensuring that encoded paths like /%61dmin are properly decoded to /admin before middleware checks. This prevents potential security issues where middleware checks might be bypassed through URL encoding.
