Immutable.js provides many Persistent Immutable data structures. Prior to versions 3.8.3, 4.3.7, and 5.1.5, Prototype Pollution is possible in immutable via the mergeDeep(), mergeDeepWith(), merge(), Map.toJS(), and Map.toObject() APIs. This issue has been patched in versions 3.8.3, 4.3.7, and 5.1.5.

According to its self-reported version number, the Atlassian Jira application running on the remote host is prior to 10.3.23 or 10.4.x prior to 11.3.8. It is, therefore, affected by multiple vulnerabilities, including flaws in bundled third-party dependencies :

- A prototype pollution vulnerability in the bundled loader-utils dependency. (CVE-2022-37601)

- A HTTP request smuggling vulnerability in the bundled Netty dependency. (CVE-2026-42581)

- A cryptographic vulnerability in the bundled Bouncy Castle dependency. (CVE-2025-14813)

- A broken authentication and session management vulnerability. (CVE-2026-29145)

- A prototype pollution vulnerability in the bundled axios dependency. (CVE-2026-42044)

- An injection vulnerability in the bundled Immutable.js dependency. (CVE-2026-29063)

- A file inclusion vulnerability in the bundled tmp dependency. (CVE-2026-44705)

- An information disclosure vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-29146)

- Multiple denial of service vulnerabilities in the bundled loader-utils dependency. (CVE-2022-37603, CVE-2022-37599)

- A file inclusion vulnerability in the bundled fast-uri dependency. (CVE-2026-6321)

- An injection vulnerability in the bundled fast-uri dependency. (CVE-2026-6322)

- A denial of service vulnerability in the bundled PostgreSQL JDBC Driver dependency. (CVE-2026-42198)

- A denial of service vulnerability in the bundled ajv dependency. (CVE-2025-69873)

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