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
Cross-site scripting vulnerability in WordPress versions prior to 6.0.3 allows a remote unauthenticated attacker to inject an arbitrary script. The developer also provides new patched releases for all versions since 3.7.

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 confidence

Cross-site scripting (XSS) vulnerability in WordPress core affecting versions prior to 6.0.3. Allows a remote unauthenticated attacker to inject arbitrary JavaScript scripts into the application, likely through a stored XSS vector given the CVSS score and description.

MitigationUpdate WordPress to version 6.0.3 or later (or the latest patched release for older version branches). All versions since 3.7 have patched releases available.

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. Determine installed WordPress version
    Access the WordPress admin dashboard and navigate to Dashboard > Home > Site Health, or check the wp-includes/version.php file for the $wp_version variable
    Affected if The version number returned is less than 6.0.3 for 6.x branches, or less than 4.8.21 for 4.8.x branches, or falls within any of these older affected ranges: < 3.7.40; >= 3.8.0 and < 3.8.40; >= 3.9.0 and < 3.9.39; >= 4.0.0 and < 4.0.37; >= 4.1.0 and < 4.1.37; >= 4.2.0 and < 4.2.34; >= 4.3.0 and < 4.3
  2. Identify the major version branch
    Look at the first two numbers of the version (for example, 4.8.20 is in the 4.8 branch, 5.8.2 is in the 5.8 branch)
    Affected if The branch is 4.8.x and version is below 4.8.21, or any 5.x or 6.0.x version below 6.0.3, or any older branch listed in the affected ranges
  3. Verify patch availability for your branch
    Check wordpress.org/news/category/security-releases/ or the release notes for your specific version branch
    Affected if Your branch does not have a corresponding patched release (for example, 4.8.21 for the 4.8 branch, or 6.0.3 for the 6.0 branch)

Your WordPress installation is affected if the installed version is less than 6.0.3 for 6.0.x/5.x branches, or less than 4.8.21 for the 4.8 branch, or falls within any of the older vulnerable version ranges listed in the CVE.

Upgrade available Upgrade to 3.7.40 / 3.8.40 / 3.9.39 or later
Fixed in 3.7.403.8.403.9.39
Interim mitigation

Update WordPress to version 6.0.3 or later (or the latest patched release for older version branches). All versions since 3.7 have patched releases available.

Recommended fix High confidence

WordPress 6.0.3 or later (latest stable release recommended)

  1. 1. Back up your WordPress database and files
  2. 2. Ensure you have a recent backup before proceeding
  3. 3. Access your WordPress admin dashboard or use FTP/sFTP to access your server
  4. 4. If using the built-in updater: Go to Dashboard > Updates and click 'Update Now' to upgrade to the latest version
  5. 5. If using FTP/sFTP: Download WordPress 6.0.3 or later from wordpress.org and upload the files, overwriting existing files
  6. 6. After upgrade, verify the site is functioning correctly
  7. 7. Clear any caching plugins or server-side caches
Caveat Minor releases like 6.0.3 typically have low risk, but always test on staging first; some plugins/themes may require updates for compatibility
