There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - compression is a Node.js and Express compression middleware. In versions before 1.8.2, when a client
    aborts the connection while a compressed response is still being sent, the zlib stream created to compress
    that response is never destroyed, so each aborted compressed response leaks its native zlib memory. A
    remote unauthenticated attacker can repeatedly open requests and disconnect early, exhausting the
    available memory and crashing the server. All applications using compression are affected. The issue is
    fixed in compression 1.8.2, and users should upgrade to 1.8.2 or later. (CVE-2026-87776)

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

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

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:87004 advisory.

    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing     IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to     individual teams, while automation developers retain the freedom to write tasks that leverage existing     knowledge without the overhead. Ansible Automation Platform makes it possible for users across an     organization to share, vet, and manage automation content by means of a simple, powerful, and agentless     language.

    Security Fix(es):

    * automation-gateway: authorization bypass via workload identity token forgery (CVE-2026-94416)
    * automation-platform-ui: proxy-addr vulnerable to IP spoofing via IPv4-mapped IPv6 trust subnet     (CVE-2026-90711)
    * automation-platform-ui: compression: Denial of Service via memory leak on premature response close     (CVE-2026-87776)
    * automation-platform-ui: fflate: Denial of Service via crafted ZIP archives (CVE-2026-45820)
    * python3.12-pulpcore: file:// scheme allowlist bypass in content upload file_url field enables arbitrary     file read and Pulp Container registry signing key theft (CVE-2026-90959)
    * python3.12-pyjwt: Verification key substitution via unvalidated JWKS redirects (CVE-2026-102267)
    * python3.12-pyjwt: Token forgery via improper Unicode byte-order mark handling (CVE-2026-102272)
