TYPO3 vulnerable to Improper Access Control of Resources Referenced by t3:// URI Scheme
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
The TYPO3-specific [`t3://` URI scheme](https://docs.typo3.org/m/typo3/reference-typoscript/main/en-us/Functions/Typolink.html#resource-references) could be used to access resources outside of the users' permission scope. This encompassed files, folders, pages, and records (although only if a valid link-handling configuration was provided). Exploiting this vulnerability requires a valid backend user account.
