SCA: security update for waku (GHSA-75w3-gmqx-993q)

medium Tenable Cloud Security Plugin ID 444536

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-49455)

Solution

Update the waku library and its related packages to version 1.0.0-beta.1 or later.
