CVE-2019-10063 describes a critical sandbox bypass vulnerability in Flatpak versions prior to 1.0.8, 1.2.4, and 1.3.1. This flaw allowed sandboxed applications to escape their confinement by exploiting an incomplete seccomp filter fix for CVE-2017-5226, specifically on 64-bit platforms. The vulnerability carries a CVSS score of 9.0 (CRITICAL) due to its network-accessible attack vector, high impact on confidentiality, integrity, and availability, and the ability to bypass security controls. While the EPSS score is low and there's no evidence of active exploitation, public exploit code, or significant community discussion, the potential for a complete sandbox escape makes it a severe risk.
