React Router is a router for React. In versions 7.7.0 through 7.13.1, when using React Router's unstable React Server Components (RSC) APIs, there is a potential client-side Cross-Site Scripting (XSS) vulnerability in the RSC redirect handling if redirects come from untrusted sources. This does not impact applications that are not using the unstable RSC APIs in React Router. This is patched in version 7.13.2.

According to its self-reported version number, the Atlassian Jira application running on the remote host is prior to 10.3.22 or 10.4.x prior to 11.3.7. It is, therefore, affected by multiple vulnerabilities, including flaws in bundled third-party dependencies :

- Multiple server-side request forgery (SSRF) vulnerabilities in the bundled axios dependency. (CVE-2026-42043, CVE-2026-42038)

- A prototype pollution vulnerability in the bundled axios dependency. (CVE-2026-40175)

- An injection vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-41293)

- A broken authentication and session management vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-43512)

- An improper authorization vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-43515)

- Multiple HTTP request smuggling vulnerabilities in the bundled Netty dependency. (CVE-2026-42584, CVE-2026-42585, CVE-2026-33870)

- Multiple injection vulnerabilities in the bundled axios dependency. (CVE-2026-42264, CVE-2026-42035, CVE-2026-42033)

- A denial of service vulnerability in the bundled Netty dependency. (CVE-2026-33871)

- A remote code execution vulnerability in the bundled react-router dependency. (CVE-2026-42211)

- A cross-site scripting (XSS) vulnerability in the bundled turbo-stream dependency. (CVE-2026-34077)

- An information disclosure vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-34487)

- A denial of service vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-41284)

- A denial of service vulnerability in the bundled nth-check dependency. (CVE-2021-3803)

- A business logic vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-43513)

- Multiple denial of service vulnerabilities in the bundled minimatch dependency. (CVE-2026-27903, CVE-2026-27904)

- A denial of service vulnerability in the bundled react-router dependency. (CVE-2026-42342)

- A cryptographic vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-34486)

- A remote code execution vulnerability in the bundled axios dependency. (CVE-2026-44495)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
