GHSA-mg66-3x8x-r8g2 TYPO3 Backend vulnerable to Frame Hijacking

• Packagist typo3/cms-backend: <= 4.0.13 (no fix yet) • Packagist typo3/cms-backend: >= 4.1.0, < 4.1.13 → fixed in 4.1.13 • Packagist typo3/cms-backend: >= 4.2.0, < 4.2.10 → fixed in 4.2.10 • Packagist typo3/cms-backend: >= 4.3alpha1, < 4.3beta2 → fixed in 4.3beta2

The Backend subcomponent in TYPO3 4.0.13 and earlier, 4.1.x before 4.1.13, 4.2.x before 4.2.10, and 4.3.x before 4.3beta2 allows remote authenticated users to place arbitrary web sites in TYPO3 backend framesets via crafted parameters, related to a "frame hijacking" issue.
