CVE-2021-27602
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.

An attacker with this authorization can inject malicious code in the source rules and perform remote code execution enabling them to compromise the confidentiality, integrity and availability of the application.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify SAP Commerce versionCheck the installed SAP Commerce version using the system information in the SAP Commerce Admin Console or by inspecting the manifest/version files in the commerce installation directoryAffected if The installed version matches 1808, 1811, 1905, 2005, or 2011 exactly
-
Confirm SAP Commerce Backoffice is in useVerify that the SAP Commerce Backoffice component is deployed and accessible in your environment by checking the Backoffice application URL or configurationAffected if Backoffice is deployed and accessible in the environment
-
Check user authorization for source rule creationReview user permissions in the Backoffice administration panel to determine if the user has the authorization required to create or modify source rules in the Drools rule engine configurationAffected if The user account has permissions to create or modify source rules within Backoffice
-
Verify source rule functionality is accessibleAttempt to access the source rule creation interface in Backoffice (typically found in the Backoffice administration under the rule engine or Drools configuration section) to confirm the feature is availableAffected if The source rule creation interface is accessible and functional in Backoffice
A system is affected if it runs SAP Commerce versions 1808, 1811, 1905, 2005, or 2011 with the Backoffice module enabled and a user account that has permissions to create source rules.
