EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3% (18th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

A path traversal vulnerability in Flatpak's handling of the export/bin directory during app deployment allows a malicious Flatpak app to cause deletion of attacker-chosen files outside the deployment directory when the app is installed or upgraded. In system-wide installations, the deletion is performed as root.
