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 2.4.7-p1, 2.4.6-p6, 2.4.5-p8, 2.4.4-p9 and earlier are affected by an Improper Restriction of Excessive Authentication Attempts vulnerability that could result in a security feature bypass. An attacker could exploit this vulnerability to perform brute force attacks and potentially gain unauthorized access to accounts. Exploitation of this issue does not require user interaction, but attack complexity is high.

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 restriction of excessive authentication attempts vulnerability where the platform fails to adequately limit or block repeated failed login attempts. This allows attackers to conduct brute force attacks against user accounts, potentially gaining unauthorized access without requiring user interaction.

MitigationImplement or enable proper account lockout mechanisms with appropriate threshold and duration settings, integrate CAPTCHA for repeated failed attempts, and configure rate limiting on authentication endpoints to prevent automated brute force attacks.

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 installed Adobe Commerce or Magento version
    Run the command 'php bin/magento --version' from the Magento root directory, or check the 'composer.json' file for the 'version' field in the root directory.
    Affected if The installed version is 2.4.3 or lower, or exactly 2.4.4, 2.4.5, 2.4.6, or 2.4.7.
  2. Verify account lockout settings in admin panel
    Log into the admin panel and navigate to Stores > Configuration > Customer > Customer Configuration > Account Lockout Options. Verify if the 'Max Login Failures to Lockout Account' is set to a non-zero value and 'Lockout Time (seconds)' is configured.
    Affected if The 'Max Login Failures to Lockout Account' is set to 0 (disabled) or is not configured, indicating no account lockout protection.
  3. Check CAPTCHA configuration for login
    Navigate to Stores > Configuration > Customer > Customer Configuration > CAPTCHA. Verify if CAPTCHA is enabled for the 'Frontend' or 'Adminhtml' login forms.
    Affected if CAPTCHA is disabled for all login forms, leaving the system reliant only on password-based authentication.
  4. Inspect authentication rate limiting configuration
    Check the web server (Apache/Nginx) configuration files or any WAF/firewall rules for rate limiting on authentication endpoints such as /customer/account/login or /admin/auth/login.
    Affected if No rate limiting rules are configured on authentication endpoints, allowing unlimited rapid login attempts.

A user is affected if their Adobe Commerce/Magento version falls within the affected range AND no account lockout, CAPTCHA, or rate limiting is configured on authentication endpoints.

Upgrade available Upgrade to a release after 2.4.3
Interim mitigation

Implement or enable proper account lockout mechanisms with appropriate threshold and duration settings, integrate CAPTCHA for repeated failed attempts, and configure rate limiting on authentication endpoints to prevent automated brute force attacks.

Recommended fix High confidence

Adobe Commerce 2.4.4-p9 / 2.4.5-p8 / 2.4.6-p6 / 2.4.7-p1 or later (or migrate to Adobe Commerce 2.4.7 which includes the fix)

  1. Identify your current Adobe Commerce or Magento version by running: php bin/magento --version
  2. For Adobe Commerce 2.4.4: Upgrade to patch version 2.4.4-p9 or later (e.g., 2.4.4-p10)
  3. For Adobe Commerce 2.4.5: Upgrade to patch version 2.4.5-p8 or later (e.g., 2.4.5-p9)
  4. For Adobe Commerce 2.4.6: Upgrade to patch version 2.4.6-p6 or later (e.g., 2.4.6-p7)
  5. For Adobe Commerce 2.4.7: Upgrade to patch version 2.4.7-p1 or later
  6. Run composer require magento/product-community-edition=2.4.4-p9 --no-update (adjust version for your baseline)
  7. Run composer update to install the patch
  8. Run php bin/magento setup:upgrade to apply database changes
Caveat Patch upgrades typically have minimal breaking changes; however, always review release notes for compatibility with custom code and third-party extensions before applying
