Cross-site scripting (XSS) vulnerability in the Extension Manager in TYPO3 6.2.x before 6.2.16 and 7.x before 7.6.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors related to extension data during an extension installation.

Multiple cross-site scripting (XSS) vulnerabilities in unspecified frontend components in TYPO3 6.2.x before 6.2.16 and 7.x before 7.6.1 allow remote authenticated editors to inject arbitrary web script or HTML via unknown vectors.

The frontend rendering component in TYPO3 4.5.x before 4.5.39, 4.6.x through 6.2.x before 6.2.9, and 7.x before 7.0.2, when config.prefixLocalAnchors is set and using a homepage with links that only contain anchors, allows remote attackers to change URLs to arbitrary domains for those links via unknown vectors.

The frontend rendering component in TYPO3 4.5.x before 4.5.39, 4.6.x through 6.2.x before 6.2.9, and 7.x before 7.0.2, when config.prefixLocalAnchors is set to all or cached, allows remote attackers to have an unspecified impact (possibly resource consumption) via a "Cache Poisoning" attack using a URL with arbitrary arguments, which triggers a reload of the page.
