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
TYPO3 is an open source web content management system. Prior to versions 8.7.47 ELTS, 9.5.34 ELTS, 10.4.29, and 11.5.11, the Form Designer backend module of the Form Framework is vulnerable to cross-site scripting. A valid backend user account with access to the form module is needed to exploit this vulnerability. TYPO3 versions 8.7.47 ELTS, 9.5.34 ELTS, 10.4.29, and 11.5.11 contain a fix for the problem.

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-79

Untrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

Recommended fix High confidence

TYPO3 8.7.47 (v8 branch), 9.5.34/35 (v9 branch), 10.4.29 (v10 branch), or 11.5.11 (v11 branch) depending on your current major version

  1. Identify your current TYPO3 version from the affected list (8.x, 9.x, 10.x, or 11.x)
  2. Determine which branch you are on (regular release or ELTS)
  3. For TYPO3 v8.x: Upgrade to version 8.7.47
  4. For TYPO3 v9.x: Upgrade to version 9.5.34 (ELTS) or 9.5.35
  5. For TYPO3 v10.x: Upgrade to version 10.4.29
  6. For TYPO3 v11.x: Upgrade to version 11.5.11
  7. Use Composer or the TYPO3 installer to perform the upgrade: `composer require typo3/cms-core:^<target-version> --with-all-dependencies`
  8. Clear all caches after upgrade
Caveat Minor version upgrades within the same major version typically have minimal breaking changes; however, review TYPO3 release notes for any deprecation warnings or configuration changes

Generated from the published advisory — verify against the referenced sources before acting.
