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
Kirby is a CMS targeting designers and editors. Kirby allows to restrict the permissions of specific user roles. Users of that role can only perform permitted actions. Permissions for creating and deleting languages have already existed and could be configured, but were not enforced by Kirby's frontend or backend code. A permission for updating existing languages has not existed before the patched versions. So disabling the languages.* wildcard permission for a role could not have prohibited updates to existing language definitions. The missing permission checks allowed attackers with Panel access to manipulate the language definitions. The problem has been patched in Kirby 3.6.6.6, Kirby 3.7.5.5, Kirby 3.8.4.4, Kirby 3.9.8.2, Kirby 3.10.1.1, and Kirby 4.3.1. Please update to one of these or a later version to fix the vulnerability. There are no known workarounds for this vulnerability.

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.

How this class of weakness works · CWE-863

An authorization check exists but is flawed, so it passes when it should fail. Attackers probe roles and object references to find the gap. Remediation means centralising and correctly implementing the access-control logic, then testing it against every role.

Recommended fix High confidence

Kirby 3.6.6.6, 3.7.5.5, 3.8.4.4, 3.9.8.2, 3.10.1.1, or 4.3.1 (choose based on your current major version branch)

  1. Back up your Kirby installation and database before updating
  2. Identify your current Kirby version from the affected versions list
  3. Upgrade to one of the fixed versions: Kirby 3.6.6.6 (if on 3.6.x), Kirby 3.7.5.5 (if on 3.7.x), Kirby 3.8.4.4 (if on 3.8.x), Kirby 3.9.8.2 (if on 3.9.x), Kirby 3.10.1.1, or Kirby 4.3.1
  4. Follow the standard Kirby upgrade procedure for your version
  5. Verify the update was successful by checking the Kirby version in the Panel
Caveat Upgrading between major version branches (e.g., 3.x to 4.x) may introduce breaking changes; review the release notes for your target version
