AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N
Network-accessible API requires admin authentication (PR:H); no user interaction; writes files but reads none (C:N); integrity fully compromised via arbitrary write (I:H).

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")).
AnalysisAI
Arbitrary file write via tar path traversal in Fledge's backup-restore API allows an authenticated admin to overwrite files anywhere on the host filesystem reachable by the Fledge process. The upload_backup() handler in backup_restore.py calls Python's tarfile.extractall() without a filter argument or member-path sanitization, enabling a classic 'tar slip' attack. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires possession of a valid Fledge admin-role account (@has_permission('admin') decorator enforces this at the API layer). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.9 (Medium) is anchored almost entirely by the PR:H requirement - the attack is gated behind admin-role authentication, which substantially limits the realistic attacker population. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patched version has been confirmed at time of analysis - the references link only to the upstream repository without a tagged fix release or advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
