CVE-2026-42190
RedwoodSDK is a server-first React framework.
Does this matter?
Lower severity and a low EPSS score (0.11%). Track it; it rarely justifies an emergency change on its own.
Description
RedwoodSDK is a server-first React framework. From version 1.0.0-beta.50 to before version 1.2.3, server actions in rwsdk apply HTTP method enforcement but no origin validation. A request originating from a different origin that the browser treats as same-site can invoke a server action with the victim's session cookie attached. This issue has been patched in version 1.2.3.
