"The version of the Tenable Identity Exposure running on the remote host is prior to 3.77.17. It is, therefore, affected by
multiple vulnerabilities according to advisory TNS-2026-11:

  - A flaw in Node.js's Permissions model allows attackers to bypass `--allow-fs-read` and `--allow-fs-write`
    restrictions using crafted relative symlink paths. By chaining directories and symlinks, a script granted
    access only to the current directory can escape the allowed path and read sensitive files. This breaks the
    expected isolation guarantees and enables arbitrary file read/write, leading to potential system compromise.
    This vulnerability affects users of the permission model on Node.js v20, v22, v24, and v25. (CVE-2025-55130)

  - Improper access control in SQL Server allows an authorized attacker to elevate privileges over a network.
    (CVE-2026-21262)

  - Improper validation of specified type of input in SQL Server allows an authorized attacker to elevate
    privileges over a network. (CVE-2026-26115)

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