RedwoodSDK is a server-first React framework.

MEDIUM 5.3EPSS 0.11%

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.
