    with maintainer-role permissions to remove certain package registry metadata that package protection rules
    restrict to higher roles, due to improper authorization checks. (CVE-2026-103549)

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

  - GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.6 before 19.2.8, 19.3 before     19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user     with maintainer-role permissions to remove certain package registry metadata that package protection rules     restrict to higher roles, due to improper authorization checks.

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

The version of GitLab installed on the remote host is affected by a vulnerability, as follows:

  - GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.6 before 19.2.8, 19.3 before     19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user     with maintainer-role permissions to remove certain package registry metadata that package protection rules     restrict to higher roles, due to improper authorization checks. (CVE-2026-103549)

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 FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 5518664d-c652-11f1-b273-2cf05da270f3 advisory.
