"The version of Atlassian Jira Service Management Data Center and Server (Jira Service Desk) running on the remote host
is affected by a vulnerability as referenced in the JSDSERVER-16596 advisory.

  - Impact: The fix for CVE-2021-23337 (https://github.com/advisories/GHSA-35jh-r3h4-6jhm) added validation
    for the variable option in _.template but did not apply the same validation to options.imports key names.
    Both paths flow into the same Function() constructor sink. When an application passes untrusted input as
    options.imports key names, an attacker can inject default-parameter expressions that execute arbitrary
    code at template compilation time. Additionally, _.template uses assignInWith to merge imports, which
    enumerates inherited properties via for..in. If Object.prototype has been polluted by any other vector,
    the polluted keys are copied into the imports object and passed to Function(). Patches: Users should
    upgrade to version 4.18.0. Workarounds: Do not pass untrusted input as key names in options.imports. Only
    use developer-controlled, static key names. (CVE-2026-4800)

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