Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
GitLab EE 12.4.2 through 12.8.1 allows Denial of Service. It was internally discovered that a potential denial of service involving permissions checks could impact a project home page.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

GitLab EE versions 12.4.2 through 12.8.1 contain a denial of service vulnerability in the permissions check logic that affects project home page rendering, allowing attackers to potentially cause service unavailability through specially crafted requests.

MitigationUpgrade GitLab EE to version 12.8.2 or later to patch the denial of service vulnerability in the permissions check functionality.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm GitLab EE is installed
    Check for the presence of GitLab by visiting the admin area or running `gitlab-rake gitlab:env:info` on the server
    Affected if GitLab EE is not installed or this command fails
  2. Retrieve the installed GitLab version
    Run `gitlab-rake gitlab:env:info` or check the GitLab admin dashboard under the version information section
    Affected if Unable to determine the version number
  3. Compare version against affected range
    Compare the installed version number to the affected range: 12.4.2 through 12.8.1 (inclusive). Note that versions below 12.4.2 and above 12.8.1 are not affected.
    Affected if The installed version is 12.4.2, 12.4.3, 12.5.0, 12.5.1, 12.5.2, 12.6.0, 12.6.1, 12.6.2, 12.6.3, 12.6.4, 12.7.0, 12.7.1, 12.7.2, 12.7.3, 12.7.4, 12.7.5, 12.7.6, 12.8.0, or 12.8.1

You are affected if your GitLab EE installation version falls between 12.4.2 and 12.8.1 inclusive.
