What is CVE-2026-96284?

A vulnerability in the Flatpak system helper allows a malicious user to gain read-access to files if a system OCI repository is configured. The issue arises when the OCI code paths in the system helper follow symlinks during the import of OCI images that are under the user's control. This behavior could lead to unauthorized access to sensitive information, highlighting the importance of proper configuration and security practices when using Flatpak.
