Summary
eZ Platform Password reset vulnerability
This Security Update fixes a severe vulnerability in the eZ Platform Admin UI, and we recommend that you install it as soon as possible. It affects eZ Platform 2.x.
The functionality for resetting a forgotten password is vulnerable to brute force attack. Depending on configuration and other circumstances an attacker may exploit this to gain control over user accounts. The update ensures such an attack is exceedingly unlikely to succeed.
You may want to consider a configuration change to further strengthen your security. By default a password reset request is valid for 1 hour. Reducing this time will make attacks even more difficult, but ensure there is enough time left to account for email delivery delays, and user delays. See documentation at https://doc.ezplatform.com/en/latest/guide/user_management/#changing-and-recovering-passwords
To install, use Composer to update to one of the "Resolving versions" mentioned above. If you use eZ Platform 2.5, update ezsystems/ezplatform-user to v1.0.1. If you use eZ Platform 2.4, update ezsystems/ezplatform-admin-ui to v1.4.6, and ezsystems/ezplatform-admin-ui-modules to v1.4.4, and ezsystems/repository-forms to v2.4.5)

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-CG84-55JX-4237? GHSA-CG84-55JX-4237 is a high-severity security vulnerability in ezsystems/ezplatform-admin-ui (composer), affecting versions >= 1.4.0, < 1.4.6. It is fixed in 1.4.6.
- Which versions of ezsystems/ezplatform-admin-ui are affected by GHSA-CG84-55JX-4237? ezsystems/ezplatform-admin-ui (composer) versions >= 1.4.0, < 1.4.6 is affected.
- Is there a fix for GHSA-CG84-55JX-4237? Yes. GHSA-CG84-55JX-4237 is fixed in 1.4.6. Upgrade to this version or later.
- Is GHSA-CG84-55JX-4237 exploitable, and should I be worried? Whether GHSA-CG84-55JX-4237 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-CG84-55JX-4237 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.
- How do I fix GHSA-CG84-55JX-4237? Upgrade
ezsystems/ezplatform-admin-uito 1.4.6 or later.
