Vulnerability from github – Published: 2021-09-02 17:16 – Updated: 2022-07-13 18:55

Summary

CSRF token exposure in TYPO3 extension

Details

When using the CsrfTokenViewHelper the extension discloses the user's session identifier to HTML output without processing of additional cryptographic hashing algorithms. This vulnerability cannot be exploited directly and occurs in combination with a chained attack - like for instance Cross Site Scripting in the frontend output.

Severity ?

6.8 (Medium)
