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 · uneditedMattermost Playbooks plugin 1.25 and earlier fails to properly restrict user-level permissions, which allows playbook members to escalate their membership privileges and perform actions restricted to playbook admins.
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 · high confidenceThe Mattermost Playbooks plugin versions 1.25 and earlier contains a broken access control vulnerability where permission checks are not properly enforced. This allows playbook members (standard users with limited privileges) to escalate their access and perform actions that should be restricted to playbook administrators, such as modifying playbook settings, managing runs, or accessing sensitive configurations.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Mattermost Playbooks plugin versionAccess the Mattermost System Console and navigate to the Plugin Management section. Locate the Playbooks plugin and note its installed version number.Affected if The installed version is 1.25.0 or any earlier version (e.g., 1.24.x, 1.23.x, etc.)
-
Confirm plugin is enabledIn the Plugin Management section of the Mattermost System Console, verify that the Playbooks plugin shows an Active status.Affected if The plugin is enabled and the version is 1.25.0 or earlier.
-
Review playbook membership assignmentsAccess individual playbooks through the Playbooks UI. For each playbook, examine the Members list to identify standard users (non-admin) who have been granted access.Affected if Standard users are present as playbook members in any playbook.
-
Audit recent playbook configuration changesReview the audit logs or playbook change history for modifications to playbook settings (such as default reminders, export settings, or webhook configurations) performed by users who should not have admin-level access.Affected if Any configuration changes were made by users who are not designated as playbook administrators.
A user is affected if the Mattermost Playbooks plugin version is 1.25.0 or earlier and standard users have access to playbooks that may have been modified beyond their intended privileges.
