GitLab has remediated an issue in GitLab EE affecting all versions from 17.8 before 18.3.6, 18.4 before 18.4.4, and 18.5 before 18.5.2 that could have allowed an authenticated attacker to leak sensitive information from confidential issues by injecting hidden prompts into merge request comments.

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

  - GitLab has remediated an issue in GitLab EE affecting all versions from 17.8 before 18.3.6, 18.4 before     18.4.4, and 18.5 before 18.5.2 that could have allowed an authenticated attacker to leak sensitive     information from confidential issues by injecting hidden prompts into merge request comments.
    (CVE-2025-6945)

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.
