There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix
    boundaries. Under `--permission`, an attacker who is granted access to one path can abuse boundary
    handling to read from or write to paths outside the intended filesystem allowlist. This vulnerability
    affects Node.js **main**, **22.x**, **24.x**, and **26.x**. (CVE-2026-58043)

  - A flaw in Node.js Permission Model enforcement allows `trace_events.createTracing().enable()` Writes Trace
    Logs Outside `--allow-fs-write`. This can lead to confidentiality impact or bypass of the intended
    security boundary under affected configurations. This vulnerability affects Node.js **22.x**, **24.x**,
    and **26.x**. (CVE-2026-56847)

  - A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual
    TLS (mTLS) client identities to be reused across requests configured with different client certificates.
    This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**. (CVE-2026-56850)

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

  - A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual     TLS (mTLS) client identities to be reused across requests configured with different client certificates.
    This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**. (CVE-2026-56850)

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

The version of Node.js installed on the remote host is prior to 22.23.2, 24.18.1, 26.5.1. It is, therefore, affected by multiple vulnerabilities as referenced in the Wednesday, July 29, 2026 Security Releases advisory.

  - A flaw in Node.js allows a spoofed TypedArray byteLength to trigger a reachable assertion in the     synchronous node:zlib APIs, causing the process to crash. Repeated exploitation of this condition can     result in a denial of service. Impact: Thank you, to byvini for reporting this vulnerability and thank you     RafaelGSS for fixing it. (CVE-2026-58045)

  - A flaw in Node.js HTTP/2 handling can let retained header blocks evade maxSessionMemory limits and cause     remote memory exhaustion. Impact: Thank you, to leduckhuong for reporting this vulnerability and thank you     mcollina for fixing it. (CVE-2026-56846)

  - A flaw in Node.js HTTP/2 handling allows nghttp2_session_mem_send() to be called re-entrantly while     nghttp2_session_mem_recv() is executing, resulting in a heap-use-after-free. Impact: Thank you, to     hahahkim for reporting this vulnerability and thank you mcollina for fixing it. (CVE-2026-56848)

  - A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix     boundaries. Under --permission, an attacker who is granted access to one path can abuse radix-tree prefix     boundary handling to read from or write to paths outside the intended filesystem allowlist. Impact: Thank     you, to sy2n0 for reporting this vulnerability and thank you RafaelGSS for fixing it. (CVE-2026-58043)

  - A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual     TLS (mTLS) client identities to be reused across requests configured with different client certificates.
    Impact: Thank you, to yottt for reporting this vulnerability and thank you RafaelGSS for fixing it.
    (CVE-2026-56850)

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