GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.1 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 to execute arbitrary JavaScript in the context of other users' browser sessions via a specially crafted repository, due to improper sanitization of HTML attributes in syntax-highlighted output.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.1 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 to
    execute arbitrary JavaScript in the context of other users' browser sessions via a specially crafted
    repository, due to improper sanitization of HTML attributes in syntax-highlighted output. (CVE-2026-92883)

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 19.1 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 to     execute arbitrary JavaScript in the context of other users' browser sessions via a specially crafted     repository, due to improper sanitization of HTML attributes in syntax-highlighted output. (CVE-2026-92883)

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 19.1 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 to     execute arbitrary JavaScript in the context of other users' browser sessions via a specially crafted     repository, due to improper sanitization of HTML attributes in syntax-highlighted output. (CVE-2026-92883)

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.
