CVE-2026-39371 is a high-severity vulnerability affecting redwoodjs redwoodsdk. It was published on April 7, 2026 and has a CVSS 3.1 base score of 8.1 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from redwoodjs. Update redwoodsdk to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
