Summary
eZ Platform Prevent accepting app.php in URL in Platform.sh
The recommended rewrite rules in eZ Platform prevent users from including the front-controller script (normally "app.php") in URLs. This prevents certain vulnerabilities related to caching. However, this is not possible when using eZ Platform Cloud (i.e. running eZ Platform on the Platform.sh cloud service), nor can it be done within the .platform.app.yaml configuration file. Therefore we need to reject such requests in the application itself. This advisory adds the prevention within the front controller script itself.
If you use eZ Platform Cloud / Platform.sh we recommend that you install this security update as soon as possible. It is distributed via Composer as ezsystems/ezplatform 1.7.9.1, and 1.13.5.1, and 2.5.4. This is the commit: https://github.com/ezsystems/ezplatform/commit/34ce86722b36a172e587068fe64a84faa7320cc2

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.

Frequently Asked Questions
- What is GHSA-QHJC-HG94-245V? GHSA-QHJC-HG94-245V is a medium-severity security vulnerability in ezsystems/ezplatform (composer), affecting versions >= 2.5.0, < 2.5.4. It is fixed in 2.5.4, 1.13.5.1, 1.7.9.1.
- Which versions of ezsystems/ezplatform are affected by GHSA-QHJC-HG94-245V? ezsystems/ezplatform (composer) versions >= 2.5.0, < 2.5.4 is affected.
- Is there a fix for GHSA-QHJC-HG94-245V? Yes. GHSA-QHJC-HG94-245V is fixed in 2.5.4, 1.13.5.1, 1.7.9.1. Upgrade to this version or later.
- Is GHSA-QHJC-HG94-245V exploitable, and should I be worried? Whether GHSA-QHJC-HG94-245V 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-QHJC-HG94-245V 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.
