How to Fix GHSA-9j39-4686-m3c4

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

ibexa/core fixed: 4.5.6 
Upgrade ibexa/core to 4.5.6
ibexa/core fixed: 4.6.2 
Upgrade ibexa/core to 4.6.2
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 ibexa/core

How to Check if You Are Affected

To determine whether your application is affected by GHSA-9j39-4686-m3c4, inspect your project dependencies for Ibexa/core:

inspect dependencies for ibexa/core

Analyze the terminal output to locate any version of Ibexa/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.5.6), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. In Ibexa/core, 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

### Impact File validation can be configured to reject certain files by file type. When this happens, validation fails, and the content can't be published. However, the file can be saved when saving the content draft. This means unwanted files can be present in storage, even if they are not easily accessible due to the content not being published. The fix ensures these unwanted file types are never stored. An attacker would need to have existing access to create content with a file field type to exploit this. ### Patches See "Patched versions".
