TYPO3 is a free and open source Content Management Framework. A vulnerability has been identified in the backend user interface functionality involving deep links. Specifically, this functionality is susceptible to Cross-Site Request Forgery (CSRF). Additionally, state-changing actions in downstream components incorrectly accepted submissions via HTTP GET and did not enforce the appropriate HTTP method. Successful exploitation of this vulnerability requires the victim to have an active session on the backend user interface and to be deceived into interacting with a malicious URL targeting the backend, which can occur under the following conditions: The user opens a malicious link, such as one sent via email. The user visits a compromised or manipulated website while the following settings are misconfigured: 1. `security.backend.enforceReferrer` feature is disabled, 2. `BE/cookieSameSite` configuration is set to lax or none The vulnerability in the affected downstream component “Form Framework Module” allows attackers to manipulate or delete persisted form definitions. Users are advised to update to TYPO3 versions 11.5.42 ELTS, 12.4.25 LTS, 13.4.3 LTS which fix the problem described. There are no known workarounds for this vulnerability.

GHSA-ww7h-g2qf-7xv6 — TYPO3 Form Framework Module vulnerable to Cross-Site Request Forgery

Affected: Packagist: typo3/cms-form

### Problem A vulnerability has been identified in the backend user interface functionality involving deep links. Specifically, this functionality is susceptible to Cross-Site Request Forgery (CSRF). Additionally, state-changing actions in downstream components incorrectly accepted submissions via HTTP GET and did not enforce the appropriate HTTP method.

Successful exploitation of this vulnerability requires the victim to have an active session on the backend user interface and to be deceived into interacting with a malicious URL targeting the backend, which can occur under the following conditions:

* the user opens a malicious link, such as one sent via email. * the user visits a compromised or manipulated website while the following settings are misconfigured: + `security.backend.enforceReferrer` feature is disabled, + `BE/cookieSameSite` configuration is set to `lax` or `none`

The vulnerability in the affected downstream component “Form Framework Module” allows attackers to manipulate or delete persisted form definitions.
