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
Applications that use GeneralUtility::sanitizeLocalUrl to allow only local URLs are vulnerable to open redirect attacks if the URL is used after it has passed the aforementioned sanitization checks. This enables attackers to redirect users to external content and carry out phishing attacks. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.

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
How this class of weakness works · CWE-601

The application redirects the browser to a URL taken from user input without validating it, so an attacker can craft a link on your trusted domain that quietly bounces victims to a malicious site. It is a staple of phishing and token theft. The fix is to allow-list redirect destinations or use indirect reference keys, never a raw user-supplied URL.

Recommended fix High confidence

Upgrade to the latest patch version in your current branch: 10.4.57+ (10.x), 11.5.51+ (11.x), 12.4.46+ (12.x), 13.4.31+ (13.x), or 14.3.3+ (14.x)

  1. 1. Identify the currently installed TYPO3 CMS version by checking the version file or TYPO3 backend
  2. 2. Determine which version branch you are currently on (10.x, 11.x, 12.x, 13.x, or 14.x)
  3. 3. For TYPO3 10.x branches: upgrade to version 10.4.57 or later
  4. 4. For TYPO3 11.x branches: upgrade to version 11.5.51 or later
  5. 5. For TYPO3 12.x branches: upgrade to version 12.4.46 or later
  6. 6. For TYPO3 13.x branches: upgrade to version 13.4.31 or later
  7. 7. For TYPO3 14.x branches: upgrade to version 14.3.3 or later
  8. 8. Test the upgrade in a staging environment before deploying to production
Caveat TYPO3 major version upgrades may introduce breaking changes; review the release notes for your specific upgrade path
