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.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1577 advisory.

    A flaw in Node.js HTTP request handling causes an uncaught TypeError when a request is received with a     header named __proto__ and the application accesses req.headersDistinct.

    When this occurs, dest[__proto__] resolves to Object.prototype rather than undefined, causing .push() to     be called on a non-array. This exception is thrown synchronously inside a property getter and cannot be     intercepted by error event listeners, meaning it cannot be handled without wrapping every     req.headersDistinct access in a try/catch.

    This vulnerability affects all Node.js HTTP servers on 20.x, 22.x, 24.x, and v25.x

    NOTE: https://nodejs.org/en/blog/vulnerability/march-2026-security-releases#denial-of-service-via-
    __proto__-header-name-in-reqheadersdistinct-uncaught-typeerror-crashes-nodejs-process-cve-2026-21710---     high (CVE-2026-21710)

    A flaw in Node.js HMAC verification uses a non-constant-time comparison when validating user-provided     signatures, potentially leaking timing information proportional to the number of matching bytes. Under     certain threat models where high-resolution timing measurements are possible, this behavior could be     exploited as a timing oracle to infer HMAC values.

    Node.js already provides timing-safe comparison primitives used elsewhere in the codebase, indicating this     is an oversight rather than an intentional design decision.

    This vulnerability affects 20.x, 22.x, 24.x, and 25.x.

    NOTE: https://nodejs.org/en/blog/vulnerability/march-2026-security-releases#timing-side-channel-in-hmac-     verification-via-memcmp-in-crypto_hmaccc-leads-to-potential-mac-forgery-cve-2026-21713---medium     (CVE-2026-21713)

    A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOW_UPDATE frames on stream 0     (connection-level) that cause the flow control window to exceed the maximum value of 231-1. The server     correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up.

    This vulnerability affects HTTP2 users on Node.js 20, 22, 24 and 25.

    NOTE: https://nodejs.org/en/blog/vulnerability/march-2026-security-releases#memory-leak-in-nodejs-     http2-server-via-window_update-on-stream-0-leads-to-resource-exhaustion-cve-2026-21714---medium     (CVE-2026-21714)

    A flaw in Node.js Permission Model filesystem enforcement leaves fs.realpathSync.native() without the     required read permission checks, while all comparable filesystem functions correctly enforce them. As a     result, code running under --permission with restricted --allow-fs-read can still use     fs.realpathSync.native() to check file existence, resolve symlink targets, and enumerate filesystem paths     outside of permitted directories.This vulnerability affects 20.x, 22.x, 24.x, and 25.x processes using the     Permission Model where --allow-fs-read is intentionally restricted.

    NOTE: https://nodejs.org/en/blog/vulnerability/march-2026-security-releases#permission-model-bypass-in-     realpathsyncnative-allows-file-existence-disclosure-cve-2026-21715---low (CVE-2026-21715)

    An incomplete fix for CVE-2024-36137 leaves FileHandle.chmod() and FileHandle.chown() in the promises API     without the required permission checks, while their callback-based equivalents (fs.fchmod(), fs.fchown())     were correctly patched.

    As a result, code running under --permission with restricted --allow-fs-write can still use promise-based     FileHandle methods to modify file permissions and ownership on already-open file descriptors, bypassing     the intended write restrictions.

    This vulnerability affects 20.x, 22.x, 24.x, and 25.x processes using the Permission Model where --allow-     fs-write is intentionally restricted.

    NOTE: https://nodejs.org/en/blog/vulnerability/march-2026-security-releases#cve-2024-36137-patch-bypass---     filehandlechmodchown-cve-2026-21716---low (CVE-2026-21716)

    A flaw in V8's string hashing mechanism causes integer-like strings to be hashed to their numeric value,     making hash collisions trivially predictable. By crafting a request that causes many such collisions in     V8's internal string table, an attacker can significantly degrade performance of the Node.js process.

    The most common trigger is any endpoint that calls JSON.parse() on attacker-controlled input, as JSON     parsing automatically internalizes short strings into the affected hash table.

    This vulnerability affects 20.x, 22.x, 24.x, and 25.x.
