"The version of JetBrains IntelliJ IDEA installed on the remote host is prior to 2026.2.1. It is, therefore, affected
by multiple vulnerabilities:

  - In JetBrains IntelliJ IDEA before 2026.2.1 RCE via Markdown export tool was possible. (CVE-2026-75056)

  - In JetBrains IntelliJ IDEA before 2026.2.1 SSRF was possible via the DevKit debug listener endpoint.
    (CVE-2026-75053)

  - In JetBrains IntelliJ IDEA before 2026.2.1 SSRF was possible via the OpenAPI preview proxy in untrusted
    projects. (CVE-2026-75054)

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