GitLab has remediated an issue in GitLab CE/EE affecting versions from 18.9 before 18.9.1 that could have under certain conditions, allowed an unauthenticated user to cause denial of service by sending specially crafted requests to a CI jobs API endpoint.

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

  - Gitlab reports: Cross-site Scripting issue in Mermaid sandbox impacts GitLab CE/EE Denial of Service issue     in container registry impacts GitLab CE/EE Denial of Service issue in Jira events endpoint impacts GitLab     CE/EE Regular Expression Denial of Service issue in GitLab merge requests impacts GitLab CE/EE Missing     rate limit in Bitbucket Server importer impacts GitLab CE/EE Denial of Service issue in CI trigger API     impacts GitLab CE/EE Denial of Service issue in token decoder impacts GitLab CE/EE Improper Access Control     issue in Conan package registry impacts GitLab EE Access Control issue in CI job mutation impacts GitLab     CE/EE (CVE-2026-1725)

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 reports: Cross-site Scripting issue in Mermaid sandbox impacts GitLab CE/EE Denial of Service issue     in container registry impacts GitLab CE/EE Denial of Service issue in Jira events endpoint impacts GitLab     CE/EE Regular Expression Denial of Service issue in GitLab merge requests impacts GitLab CE/EE Missing     rate limit in Bitbucket Server importer impacts GitLab CE/EE Denial of Service issue in CI trigger API     impacts GitLab CE/EE Denial of Service issue in token decoder impacts GitLab CE/EE Improper Access Control     issue in Conan package registry impacts GitLab EE Access Control issue in CI job mutation impacts GitLab     CE/EE (CVE-2026-1725)

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 102a03c9-1316-11f1-93ca-2cf05da270f3 advisory.

    Gitlab reports:
    Cross-site Scripting issue in Mermaid sandbox impacts GitLab CE/EE     Denial of Service issue in container registry impacts GitLab CE/EE     Denial of Service issue in Jira events endpoint impacts GitLab CE/EE     Regular Expression Denial of Service issue in GitLab merge requests impacts GitLab CE/EE     Missing rate limit in Bitbucket Server importer impacts GitLab CE/EE     Denial of Service issue in CI trigger API impacts GitLab CE/EE     Denial of Service issue in token decoder impacts GitLab CE/EE     Improper Access Control issue in Conan package registry impacts GitLab EE     Access Control issue in CI job mutation impacts GitLab CE/EE

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