8.1 highCVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:HCVE-2026-39371
High (8.1) in redwoodjs redwoodsdk. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in rwsdk 1.0.6.
RedwoodSDK is a server-first React framework. From 1.0.0-beta.50 to 1.0.5, erver functions exported from "use server" files could be invoked via GET requests, bypassing their intended HTTP method. In cookie-authenticated applications, this allowed cross-site GET navigations to trigger state-changing functions, because browsers send SameSite=Lax cookies on top-level GET requests. This affected all server functions -- both serverAction() handlers and bare exported functions in "use server" files. This vulnerability is fixed in 1.0.6.
