CVE-2026-97023: Flatpak path traversal in export/bin directory handling

CVE-2026-97023 · Severity: high · CVSS 7.1 · Published 2026-09-28

Flatpak, a system for sandboxing and deploying Linux applications, contains a path traversal vulnerability in how it handles the export/bin directory during app installation or upgrade. A malicious Flatpak app can exploit this to delete arbitrary files outside its deployment directory; on system-wide installations, these deletions occur with root privileges, potentially causing severe data loss or system disruption.

Technical details

A path traversal flaw in Flatpak's export/bin directory processing allows a malicious app to craft symlinks that escape the deployment sandbox and target files elsewhere on the filesystem. The vulnerability requires user interaction (installing or upgrading an app) but no authentication; in system-wide deployments, operations are performed as root, amplifying impact. An attacker can cause arbitrary file deletion, with a fix expected from upstream.
