CVE-2026-42190: CWE-352: Cross-Site Request Forgery (CSRF) in redwoodjs sdk
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.
AI Analysis
Technical Summary
RedwoodJS SDK versions >= 1.0.0-beta.50 and < 1.2.3 have a CSRF vulnerability (CWE-352) where server actions enforce HTTP methods but lack origin validation. This permits cross-origin requests that browsers consider same-site to execute server actions using the victim's session cookie. The vulnerability is fixed in version 1.2.3.
Potential Impact
An attacker can trick a victim into submitting a request from a different origin that the browser treats as same-site, causing unauthorized server actions to be executed with the victim's session cookie. This can lead to unauthorized state changes or actions within the application. Confidentiality and availability are not impacted, but integrity is compromised.
Mitigation Recommendations
Upgrade RedwoodJS SDK to version 1.2.3 or later, where this CSRF vulnerability has been patched. No other mitigation is indicated by the vendor advisory.
