Typo3 : Security Vulnerabilities, CVEs, Published In 2019 (Sql injection) CVSS score >= 7

An issue was discovered in TYPO3 before 8.7.30, 9.x before 9.5.12, and 10.x before 10.2.2. Because escaping of user-submitted content is mishandled, the class QueryGenerator is vulnerable to SQL injection. Exploitation requires having the system extension ext:lowlevel installed, and a valid backend user who has administrator privileges.

It was found that Typo3 Core versions 4.5.0 - 4.5.5 uses prepared statements that, if the parameter values are not properly replaced, could lead to a SQL Injection vulnerability. This issue can only be exploited if two or more parameters are bound to the query and at least two come from user input.

TYPO3 before 4.1.14, 4.2.x before 4.2.13, 4.3.x before 4.3.4 and 4.4.x before 4.4.1 allows SQL Injection on the backend.
