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
Improper access control in mail module (channel partners) in Odoo Community 14.0 and earlier and Odoo Enterprise 14.0 and earlier, allows remote authenticated users to subscribe to arbitrary mail channels uninvited.

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 confidence

Odoo fails to enforce proper authorization checks when users attempt to subscribe to mail channels. Authenticated users can subscribe to any channel without invitation by manipulating the subscription request, bypassing the intended access control that should require an invitation or appropriate permissions.

MitigationImplement server-side validation to verify that the requesting user has proper permissions or an existing invitation before allowing channel subscription. Restrict channel subscription to invited users only.

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. Check installed Odoo version
    Access Odoo via UI (About Odoo in Settings) or check the odoo-bin --version output, or inspect the odoo/release.py file for the version number
    Affected if The installed version is 14.0 or earlier (any version listed as 14.0, 13.0, 12.0, etc.)
  2. Verify mail channel module is active
    Navigate to Apps menu in Odoo and search for 'Mail' or 'Discuss' module, or check the 'discuss' addon is present in the addons path
    Affected if The mail/discuss channel module is installed and in use on the instance
  3. Check channel subscription access rights
    Review the discuss.channel model access rights in Odoo: go to Settings > Technical > Security > Access Rights, or inspect ir.model.access records for 'discuss.channel'
    Affected if The access rights allow authenticated users (without specific channel invitation) to create or write to discuss.channel subscription records, or no invitation-based validation is enforced
  4. Inspect subscription request handling
    Review the controller or model method handling channel subscription (typically in addons/discuss/controllers or addons/mail/models), look for code that processes subscription requests
    Affected if The subscription logic lacks server-side validation to check for valid invitation or proper channel permissions before allowing subscription

The environment is affected if running Odoo version 14.0 or earlier with the mail/discuss module active, where the channel subscription feature lacks proper invitation-based authorization checks.

Interim mitigation

Implement server-side validation to verify that the requesting user has proper permissions or an existing invitation before allowing channel subscription. Restrict channel subscription to invited users only.
