How to Fix GHSA-7vwg-39h8-8qp8

To remediate this vulnerability, upgrade all affected Ezsystems/ezplatform rest 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-rest fixed: 1.2.2.1 
Upgrade ezsystems/ezplatform-rest to 1.2.2.1
ezsystems/ezplatform-rest fixed: 1.3.1.1 
Upgrade ezsystems/ezplatform-rest to 1.3.1.1
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-rest

How to Check if You Are Affected

To determine whether your application is affected by GHSA-7vwg-39h8-8qp8, inspect your project dependencies for Ezsystems/ezplatform rest:

inspect dependencies for ezsystems/ezplatform-rest

Analyze the terminal output to locate any version of Ezsystems/ezplatform rest in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.2.1), 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-203: Observable Discrepancy, where the product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. In Ezsystems/ezplatform rest, 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 a vulnerability in eZ Platform v1.13, v2.5, and v3.2, and in Ibexa DXP and Ibexa Open Source v3.3. The /user/sessions endpoint can let an attacker detect if a given username or email refers to a valid account. This can be detected through differences in the response data or response time of certain requests. The fix ensures neither attack is possible. The fix is distributed via Composer.
