GHSA-7QWG-FCPW-XG5G

Privilege Escalation & SQL Injection in TYPO3 CMS

Failing to properly dissociate system related configuration from user generated configuration, the Form Framework (system extension "form") is vulnerable to SQL injection and Privilege Escalation. Basically instructions can be persisted to a form definition file that were not configured to be modified - this applies to definitions managed using the form editor module as well as direct file upload using the regular file list module. A valid backend user account as well as having system extension form activated are needed in order to exploit this vulnerability.

Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.

GHSA-7QWG-FCPW-XG5G has a CVSS score of 8.8 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (8.7.17, 9.3.2); upgrading removes the vulnerable code path.

1. What is GHSA-7QWG-FCPW-XG5G? GHSA-7QWG-FCPW-XG5G is a high-severity code injection vulnerability in typo3/cms (composer), affecting versions >= 8.5.0, < 8.7.17. It is fixed in 8.7.17, 9.3.2. Untrusted input is evaluated as executable code within the application's runtime environment.
2. How severe is GHSA-7QWG-FCPW-XG5G? GHSA-7QWG-FCPW-XG5G has a CVSS score of 8.8 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of typo3/cms are affected by GHSA-7QWG-FCPW-XG5G? typo3/cms (composer) versions >= 8.5.0, < 8.7.17 is affected.
4. Is there a fix for GHSA-7QWG-FCPW-XG5G? Yes. GHSA-7QWG-FCPW-XG5G is fixed in 8.7.17, 9.3.2. Upgrade to this version or later.
5. Is GHSA-7QWG-FCPW-XG5G exploitable, and should I be worried? Whether GHSA-7QWG-FCPW-XG5G is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether GHSA-7QWG-FCPW-XG5G is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix GHSA-7QWG-FCPW-XG5G?
   • Upgrade typo3/cms to 8.7.17 or later
   • Upgrade typo3/cms to 9.3.2 or later
