GitLab has remediated an issue in GitLab CE/EE affecting all versions from 12.3 before 18.6.4, 18.7 before 18.7.2, and 18.8 before 18.8.2 that could have allowed an unauthenticated user to create a denial of service condition by sending repeated malformed SSH authentication requests.

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 12.3 before 18.6.4, 18.7 before     18.7.2, and 18.8 before 18.8.2 that could have allowed an unauthenticated user to create a denial of     service condition by sending repeated malformed SSH authentication requests. (CVE-2026-1102)

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.

  - GitLab has remediated an issue in GitLab CE/EE affecting all versions from 12.3 before 18.6.4, 18.7 before     18.7.2, and 18.8 before 18.8.2 that could have allowed an unauthenticated user to create a denial of     service condition by sending repeated malformed SSH authentication requests. (CVE-2026-1102)

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

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 61dc7f67-f6e5-11f0-b051-2cf05da270f3 advisory.

    Gitlab reports:
    Denial of Service issue in Jira Connect integration impacts GitLab CE/EE     Incorrect Authorization issue in Releases API impacts GitLab CE/EE     Unchecked Return Value issue in authentication services impacts GitLab CE/EE     Infinite Loop issue in Wiki redirects impacts GitLab CE/EE     Denial of Service issue in API endpoint impacts GitLab CE/EE

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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