Summary
Typo3 Information Disclosure in Backend User Interface
The element information component used to display properties of a certain record is susceptible to information disclosure. The list of references from or to the record is not properly checked for the backend user’s permissions. A valid backend user account is needed in order to exploit this vulnerability.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- Which versions of typo3/cms are affected by GHSA-Q9C4-9V5M-597P? typo3/cms (composer) versions >= 8.0.0, < 8.7.27 is affected.
- Is there a fix for GHSA-Q9C4-9V5M-597P? Yes. GHSA-Q9C4-9V5M-597P is fixed in 8.7.27, 9.5.8. Upgrade to this version or later.
- Is GHSA-Q9C4-9V5M-597P exploitable, and should I be worried? Whether GHSA-Q9C4-9V5M-597P 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.

- What actually determines whether GHSA-Q9C4-9V5M-597P 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.
