Summary
Workarounds
None, other than blocking all downloads.
References
Impact
The route used for file downloads allows specifying the name of the downloaded file. This is an unintended side effect of the implementation, and means one could construct download URLs with filenames that have no relation to the actual file, which could lead to misunderstandings and confusion, and possibly other harm. As such it is a low severity vulnerability. It affects all supported versions of Ibexa DXP and eZ Platform, in installations where downloadable files exist.

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.
Remediation advice
The issue is fixed in all supported versions of ezsystems/ezpublish-kernel, see "Patched versions".
An advisory is also published for ezsystems/ezplatform-kernel and ibexa/core, please see those repositories.

Frequently Asked Questions
- What is GHSA-946C-F9W6-2C25? GHSA-946C-F9W6-2C25 is a low-severity security vulnerability in ezsystems/ezpublish-kernel (composer), affecting versions >= 7.5.0, < 7.5.31. It is fixed in 7.5.31.
- Which versions of ezsystems/ezpublish-kernel are affected by GHSA-946C-F9W6-2C25? ezsystems/ezpublish-kernel (composer) versions >= 7.5.0, < 7.5.31 is affected.
- Is there a fix for GHSA-946C-F9W6-2C25? Yes. GHSA-946C-F9W6-2C25 is fixed in 7.5.31. Upgrade to this version or later.
- Is GHSA-946C-F9W6-2C25 exploitable, and should I be worried? Whether GHSA-946C-F9W6-2C25 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-946C-F9W6-2C25 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-946C-F9W6-2C25? Upgrade
ezsystems/ezpublish-kernelto 7.5.31 or later.
