CyberRota Analysis
AI-GeneratedThe unstable_redirect() helper in Waku prior to version 1.0.0-beta.1 is vulnerable to open redirect attacks due to the lack of URL validation, allowing arbitrary strings to be reflected in the HTTP Location response header. This vulnerability can be exploited by attackers to redirect users to malicious external domains, facilitating phishing and credential theft. Developers using affected versions should prioritize upgrading to the patched version to mitigate these risks.

Original NVD Description
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.
