"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.
