Waku is the minimal React framework. Prior to version 1.0.0-beta.1, Waku’s RSC request dispatcher invokes server actions without validating the request’s Origin (or Sec-Fetch-Site) header. A cross-origin web attacker can therefore cause a victim browser to issue an authenticated POST to a registered server action endpoint using a CORS-safelisted content type (text\/plain), which does not trigger a preflight. Any state-mutating server action that the application exposes via ‘use server’ can be invoked with the victim’s cookies attached. This issue has been patched in version 1.0.0-beta.1.<\/p>\n","protected":false},"excerpt":{"rendered":"
