Answer in brief
CVE-2026-71283 records a Medium severity (CVSS 4.9) vulnerability in Fledge IoT Gateway Backup Restore Tar Path Traversal. The current sources do not mark it as known exploited. The current feed maps fledge-iot/fledge (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 4.9. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Fledge's backup-restore upload handler, upload_backup() (python/fledge/services/core/api/backup_restore.py), calls tarfile.extractall(temp_path) on an admin-uploaded tar archive with no filter argument and no per-member path validation. A crafted tar archive containing member names with `../` path components extracts files outside the intended temporary directory, allowing arbitrary file writes anywhere on the filesystem reachable by the Fledge process. Requires the admin role (@has_permission("admin")).
