CVE-2022-34257
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 · uneditedAdobe Commerce versions 2.4.3-p2 (and earlier), 2.3.7-p3 (and earlier) and 2.4.4 (and earlier) are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.
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 · high confidenceStored Cross-Site Scripting (XSS) vulnerability in Adobe Commerce (Magento) affecting versions 2.4.3-p2 and earlier, 2.3.7-p3 and earlier, and 2.4.4 and earlier. Attackers can inject malicious JavaScript into vulnerable form fields which executes in victims' browsers when viewing affected pages.

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.
-
Check installed Adobe Commerce or Magento versionRun the CLI command: php bin/magento --version or check the composer.json file for the version entryAffected if The version is 2.4.3-p2 or earlier, 2.3.7-p3 or earlier, or exactly 2.4.4 (versions 2.3.0 through 2.3.6, 2.3.7, 2.4.0 through 2.4.3-p1, 2.4.3, or 2.4.4)
-
Identify admin-accessible form fieldsReview custom or third-party module form configurations in app/code and vendor directories, looking for form UI components in etc/adminhtml/ui_component/*.xml files that accept user input without proper sanitizationAffected if Form fields exist that accept user input and lack output encoding or input validation in their data persistence logic
-
Verify if custom or third-party modules handle form input safelySearch the codebase for form field handlers in controllers or data providers, checking if they use methods like $this->escapeHtml(), htmlSpecialChars(), or other sanitization before saving to databaseAffected if Form handlers save user input without sanitizing HTML or JavaScript characters
-
Confirm stored XSS is exploitableAs an admin user, attempt to inject a test script tag into any custom form fields and verify whether the tag renders as raw HTML or gets executed when the page is viewedAffected if Injected script tags or event handlers are rendered unescaped in the frontend or admin panel
The environment is affected if the Adobe Commerce/Magento version falls within the listed vulnerable versions AND custom form fields exist that do not sanitize user input before storage.
Generated from the published advisory. Verify against your own configuration.
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 · scoped2.3.72.4.3
Update Adobe Commerce to the latest patched version. Additionally, implement proper input validation and output encoding on affected form fields to prevent XSS injection.
Magento/Open Source 2.4.5 or higher / Adobe Commerce 2.4.5 or higher (or appropriate patched version for 2.3.x line such as 2.3.7-p4 or later)
- 1. Backup the current Adobe Commerce/Magento database and files
- 2. Review the current installed version using bin/magento --version
- 3. Update composer.json to require the fixed version: composer require magento/product-community-edition=2.4.5 --no-update (or appropriate version for your license type)
- 4. Run composer update to fetch new packages
- 5. After composer update completes, run bin/magento setup:upgrade to apply database migrations
- 6. Clear caches: bin/magento cache:flush
- 7. Re-index: bin/magento indexer:reindex
- 8. Verify the upgrade was successful and test the application
