Description


Some vulnerabilities have been reported in Typo3, which can be exploited by malicious people to conduct cross-site scripting attacks and disclose sensitive information.

2) An error in the "jumpUrl" mechanism can be exploited to read arbitrary files from local resources by disclosing a hash secret used to restrict file access.
