The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value (e.g., `{1..2..0}`) causes the sequence generation loop to run indefinitely, making the process hang for seconds and allocate heaps of memory. Versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13 fix the issue. As a workaround, sanitize strings passed to `expand()` to ensure a step value of `0` is not used.

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-16574 advisory.

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

The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in the CONFSERVER-103710 advisory.

  - This DoS (Denial of Service) vulnerability allows an unauthenticated attacker to cause a resource to be     unavailable for its intended users by temporarily or indefinitely disrupting services of a host connected     to a network which has no impact to confidentiality, no impact to integrity, high impact to availability,     and requires no user interaction. (CVE-2026-33750)

Note that Nessus has not tested for this issue 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.
