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
Adobe Commerce versions 2.4.3-p2 (and earlier), 2.3.7-p3 (and earlier) and 2.4.4 (and earlier) are affected by an Improper Authorization vulnerability that could result in Privilege escalation. An attacker could leverage this vulnerability to access other user's data. Exploitation of this issue does not require user interaction.

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 · moderate confidence

Adobe Commerce contains an Improper Authorization vulnerability allowing privilege escalation. Unauthenticated attackers can access other users' data by exploiting insufficient authorization checks in the application. The CVSS 9.8 indicates this is a remotely exploitable, low-complexity issue with critical impact requiring no user interaction.

MitigationUpgrade Adobe Commerce to version 2.4.3-p3 or later for the 2.4.x branch, or 2.3.7-p4 or later for the 2.3.x branch to obtain the patched authorization controls.

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. Identify the installed Adobe Commerce or Magento version
    Run the command 'php bin/magento --version' from the web root directory, or check the file 'composer.json' for the 'version' field under 'require' for 'magento/product-community-edition' or 'magento/product-enterprise-edition'
    Affected if The version shown is 2.3.0 through 2.3.7, or 2.4.0 through 2.4.4 (excluding patched versions 2.3.7-p4+ and 2.4.3-p3+)
  2. Confirm the product edition
    Check composer.json for the package name: 'magento/product-community-edition' indicates Magento Open Source, 'magento/product-enterprise-edition' or 'adobe-commerce' indicates Adobe Commerce
    Affected if The product is either Adobe Commerce or Magento (both use the same vulnerable code)
  3. Verify the patch is not applied
    Check for the existence of the file 'app/etc/patches/.applied' or run 'bin/magento support:patch:list' to see applied security patches
    Affected if No security patch for CVE-2022-34256 is listed as applied, or the file does not exist indicating patches have not been run

Your environment is affected if Adobe Commerce or Magento is installed at version 2.3.0-2.3.7 or 2.4.0-2.4.4 and no corresponding security patch has been applied.

Upgrade available Upgrade to 2.3.7 / 2.4.3 or later
Fixed in 2.3.72.4.3
Interim mitigation

Upgrade Adobe Commerce to version 2.4.3-p3 or later for the 2.4.x branch, or 2.3.7-p4 or later for the 2.3.x branch to obtain the patched authorization controls.

Recommended fix High confidence

2.4.4 (or 2.4.3-p3 for patch-only path; 2.3.7-p4 for 2.3.x branch)

  1. 1. Backup your Adobe Commerce/Magento database and files
  2. 2. Put the store in maintenance mode to prevent user access during upgrade
  3. 3. Run composer require magento/product-community-edition=2.4.4 --no-update (or appropriate version for your branch)
  4. 4. Run composer update to fetch the new packages
  5. 5. Run bin/magento setup:upgrade to apply database migrations
  6. 6. Run bin/magento cache:flush to clear cached data
  7. 7. Verify the upgrade by checking the admin panel and frontend
  8. 8. Take the store out of maintenance mode
Caveat Security patch releases typically have minimal breaking changes; however, always test in a staging environment first as custom extensions may require compatibility updates
