SCA: security update for waku (GHSA-43fc-v873-qw85)

low Tenable Cloud Security Plugin ID 444530

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, the unstable_redirect() helper
exported from waku/router/server (packages/waku/src/router/define-router.tsx:156–161) accepts an arbitrary
string and reflects it unchanged into the HTTP Location response header with no URL validation, scheme
restriction, or path-only enforcement. Any application that passes user-controlled input to this helper —
the natural pattern documented in the JSDoc and official fixtures — is vulnerable to open redirect
attacks. An attacker who convinces a victim to click a crafted link can silently redirect the browser to
an arbitrary external domain, enabling phishing, credential harvesting, and OAuth token theft.
Additionally, scheme-relative URLs (//evil.example/) bypass naive https?://-only allow-list filters that
developers might add as ad-hoc mitigations. This issue has been patched in version 1.0.0-beta.1.
(CVE-2026-49456)

Solution

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