CVE-2023-0456
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 · uneditedA flaw was found in APICast, when 3Scale's OIDC module does not properly evaluate the response to a mismatched token from a separate realm. This could allow a separate realm to be accessible to an attacker, permitting access to unauthorized information.
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.

dbcve · scoped2.12.22.13.2
Upgrade to APICast version 2.12.2 or 2.13.2 (or latest available stable release)
- 1. Identify your current APICast/3scale version by checking your deployment configuration or running 'apicast --version'
- 2. If running version < 2.12.2, plan upgrade to version 2.12.2 or later
- 3. If running version >= 2.13.0 and < 2.13.2, plan upgrade to version 2.13.2 or later
- 4. Backup your current configuration and any custom policies before upgrading
- 5. Consult Red Hat 3scale API Management upgrade documentation for your deployment method (operator-based or YAML-based)
- 6. Apply the upgrade following Red Hat's standard upgrade procedure for your environment
- 7. After upgrade, verify OIDC authentication is functioning correctly by testing token validation across different realms
- 8. Confirm the fix by verifying the version matches a fixed release (2.12.2+ or 2.13.2+)
