"The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in
the CONFSERVER-99686 advisory.

  - Improper Input Validation vulnerability in Apache Tomcat. Incorrect error handling for some invalid HTTP
    priority headers resulted in incomplete clean-up of the failed request which created a memory leak. A
    large number of such requests could trigger an OutOfMemoryException resulting in a denial of service. This
    issue affects Apache Tomcat: from 9.0.76 through 9.0.102, from 10.1.10 through 10.1.39, from 11.0.0-M2
    through 11.0.5. Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6 which fix the
    issue. (CVE-2025-31650)

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