A malicious or compromised Flatpak app could exploit this to achieve arbitrary code execution on the host. (CVE-2026-34078, GHSA-cc2q-qc34-jprg) (Closes: #1132943) - Prevent arbitrary file deletion outside the sandbox by a malicious or compromised Flatpak app (CVE-2026-34079, GHSA-p29x-r292-46pp) (Closes: #1132944) - Prevent a local user from reading any file that is readable by the _flatpak system user. A mitigation is that it would be very unusual for these files not to be readable by the original local user as well.
