DescriptionGitHub Advisory
Hono is a Web application framework that provides support for any JavaScript runtime. Prior to version 4.11.7, a Cross-Site Scripting (XSS) vulnerability exists in the ErrorBoundary component of the hono/jsx library. Under certain usage patterns, untrusted user-controlled strings may be rendered as raw HTML, allowing arbitrary script execution in the victim's browser. Version 4.11.7 patches the issue.
AnalysisAI
Hono's ErrorBoundary JSX component before version 4.11.7 fails to properly sanitize user-controlled input, allowing attackers to inject and execute arbitrary JavaScript in victims' browsers through reflected XSS. The vulnerability requires user interaction and network access but can compromise the confidentiality and integrity of affected applications. A patch is available in version 4.11.7.
