What is CVE-2026-42190?

RedwoodSDK is a server-first React framework that has a vulnerability allowing unauthorized server actions. This issue arises due to the lack of origin validation, which permits requests from different origins that the browser classifies as same-site. Consequently, an attacker could exploit this to trigger server actions while including the victim's session cookies. The vulnerability is resolved in version 1.2.3, which implements necessary origin checks.

Affected Version(s)

sdk >= 1.0.0-beta.50, < 1.2.3
