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 analysisThe application confirms who you are but does not properly check whether you are permitted to perform a given action, so authenticated users reach functions or data meant for others. Attackers test roles and object references to find the gap. Remediation is an authorization check on every request, evaluated against the acting user's actual permissions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.812.0
- 1. Back up your current Casdoor installation and database before upgrading
- 2. Upgrade Casdoor to version 1.812.0 by pulling the latest image or using your deployment method (e.g., docker pull casbin/casdoor:v1.812.0 or git checkout to the v1.812.0 tag)
- 3. Restart the Casdoor service to apply the upgrade
- 4. Verify the upgrade was successful by checking the version number in the UI or via API
- 5. Test the SCIM endpoint functionality to confirm the authorization bypass is resolved
