How to Fix GHSA-2w9p-xxqr-h253

To remediate this vulnerability, upgrade all affected Ezsystems/ezplatform kernel dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ezsystems/ezplatform-kernel fixed: 1.0.3 
Upgrade ezsystems/ezplatform-kernel to 1.0.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for ezsystems/ezplatform-kernel

How to Check if You Are Affected

To determine whether your application is affected by GHSA-2w9p-xxqr-h253, inspect your project dependencies for Ezsystems/ezplatform kernel:

inspect dependencies for ezsystems/ezplatform-kernel

Analyze the terminal output to locate any version of Ezsystems/ezplatform kernel in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Ezsystems/ezplatform kernel, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

This Security Advisory is about an object injection vulnerability in the SiteAccessMatchListener of eZ Platform, which could lead to remote code execution (RCE), a very serious threat. All sites may be affected. Update: There are bugs introduced by this fix, particularly but not limited to compound siteaccess matchers. These have been fixed in ezsystems/ezplatform-kernel v1.0.3, and in ezsystems/ezpublish-kernel v7.5.8, v6.13.6.4, and v5.4.15.
