"The version of OISF Suricata installed on the remote host is prior to 7.0.16 or 8.x prior to 8.0.5. It is,
therefore, affected by multiple vulnerabilities, including:

  - A protocol change while processing HTTP/2 traffic could lead to type confusion in Suricata. Crafted traffic
    may cause Suricata to crash, resulting in denial of service. (CVE-2026-45764)

  - Suricata's HTTP/2 decompression path could grow the decompressed response-body buffer without an effective
    upper bound. A crafted HTTP/2 DATA payload using a high compression ratio, such as gzip, deflate, or brotli
    compressed data, could cause Suricata to allocate excessive memory while decompressing the payload.
    (CVE-2026-46387)

  - Suricata could repeatedly perform expensive parsing of large HTTP Content-Disposition headers during HTTP
    response body processing. Crafted HTTP traffic could cause excessive CPU usage and denial of service.
    (CVE-2026-45759)

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