    (CVE-2019-7740)

  - Inadequate checks at the Global Configuration helpurl settings allowed stored XSS. (CVE-2019-7741)

  - A combination of specific web server configurations, in connection with specific file types and browser-side
    MIME-type sniffing, causes an XSS attack vector. (CVE-2019-7742)

  - The phar:// stream wrapper can be used for objection injection attacks because there is no protection
    mechanism (such as the TYPO3 PHAR stream wrapper) to prevent use of the phar:// handler for non .phar-files.
    (CVE-2019-7743)
