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

  - daphne before 4.2.2 did not pass maxFramePayloadSize or maxMessagePayloadSize to Autobahn's
    WebSocketServerFactory. Because Autobahn defaults both values to 0 (unlimited), an unauthenticated remote
    attacker could send arbitrarily large WebSocket messages or frames, causing excessive memory consumption
    and a denial of service. (CVE-2026-44545)

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

  - daphne before 4.2.2 did not pass maxFramePayloadSize or maxMessagePayloadSize to Autobahn's
    WebSocketServerFactory. Because Autobahn defaults both values to 0 (unlimited), an unauthenticated remote
    attacker could send arbitrarily large WebSocket messages or frames, causing excessive memory consumption
    and a denial of service. (CVE-2026-44545)

  - daphne before 4.2.2 reconstructs a raw HTTP request from Twisted's parsed headers and feeds it to autobahn
    for WebSocket handshake processing. Twisted does not treat \x0b, \x0c, \x1c, \x1d, \x1e, or \x85 as header
    line separators, but autobahn decodes header values to str and calls splitlines(). An attacker can exploit
    this parser differential to inject additional headers into the ASGI scope passed to the application.
    daphne now rejects requests with these bytes in any header value with a 400 response. (CVE-2026-44546)

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:50336 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-controller: PyJWT: Authentication bypass due to forged JSON Web Tokens (CVE-2026-48526)
    * automation-eda-controller: ExternalEventStreamViewSet trusts Subject header without validation and leaks     expected DN (CVE-2026-12383)

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

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

  - daphne before 4.2.2 did not pass maxFramePayloadSize or maxMessagePayloadSize to Autobahn's     WebSocketServerFactory. Because Autobahn defaults both values to 0 (unlimited), an unauthenticated remote     attacker could send arbitrarily large WebSocket messages or frames, causing excessive memory consumption     and a denial of service. (CVE-2026-44545)

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