CVE-2021-36029
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 · uneditedMagento Commerce versions 2.4.2 (and earlier), 2.4.2-p1 (and earlier) and 2.3.7 (and earlier) are affected by an improper improper authorization vulnerability. An attacker with admin privileges could leverage this vulnerability to achieve remote code execution.
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 · scopedAdobe Commerce/Magento Open Source 2.4.3 or 2.3.7-p1
- Confirm current Adobe Commerce or Magento Open Source version by running: bin/magento --version
- Backup the Magento database and files before proceeding with upgrade
- For Adobe Commerce (on-premise): Run composer require magento/product-community-edition=2.4.3 --no-update followed by composer update
- Alternatively, apply the security patch APSB21-64 which addresses this vulnerability
- After upgrade/patch, clear the cache: bin/magento cache:flush
- Verify the admin user roles and permissions are correctly configured
- Test that admin privilege escalation is no longer possible
