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

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. (CVE-2025-55130)

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

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

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)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in Erlang OTP (inets     httpd module) allows HTTP Request Smuggling. This vulnerability is associated with program files     lib/inets/src/http_server/httpd_request.erl and program routines httpd_request:parse_headers/7. The server     does not reject or normalize duplicate Content-Length headers. The earliest Content-Length in the request     is used for body parsing while common reverse proxies (nginx, Apache httpd, Envoy) honor the last Content-     Length value. This violates RFC 9112 Section 6.3 and allows front-end/back-end desynchronization, leaving     attacker-controlled bytes queued as the start of the next request. This issue affects OTP from OTP 17.0     before OTP 28.4.1, OTP 27.3.4.9 and OTP 26.2.5.18, corresponding to inets from 5.10 before 9.6.1, 9.3.2.3     and 9.1.0.5. (CVE-2026-23941)

Note that Nessus relies on the presence of the package as reported by the vendor.
