CVE-2026-72577: NASA fprime-gds - Missing Authentication and Path Traversal Enable Unauthenticated RCE and Spacecraft Command Injection
Multiple vulnerabilities in NASA fprime-gds through 3.4.3 allow an unauthenticated remote attacker to achieve arbitrary code execution on the ground station host and inject arbitrary commands to connected spacecraft. The Flask application in src/fprime_gds/flask/app.py applies no authentication to any endpoint.
Security readout for executives and security teams
Plain-English summary
NASA fprime-gds through 3.4.3 reportedly exposes ground-station functions without authentication. A remote attacker reaching the Flask service could compromise its host and send unauthorized commands to connected spacecraft. This creates severe operational, safety, confidentiality, integrity, and availability risk.
Executive priority
Treat as an immediate incident-prevention priority wherever fprime-gds is deployed. Isolate reachable services, identify spacecraft-connected instances, and assign engineering and mission-operations owners. Consider incident response if an affected service was exposed, because the potential impact includes host takeover and unauthorized spacecraft control.
Technical view
The supplied CVE describes missing authentication across Flask endpoints, combined with path traversal, enabling unauthenticated remote code execution and spacecraft command injection. CVSS 3.1 is 9.8: network-accessible, low complexity, no privileges or user interaction, with high impact. The source bundle identifies CWE-306 but provides incomplete structured version data.
Likely exposure
Highest exposure exists where the fprime-gds Flask service is reachable from untrusted or insufficiently segmented networks. Systems connected to spacecraft or running with valuable host privileges have especially serious consequences. The bundle says versions through 3.4.3 are affected, although its structured affected-version entry is inconsistent and marked unknown.
Exploitation context
The bundle does not establish active exploitation, and KEV is false. Exploitation is nevertheless described as remotely reachable, unauthenticated, low complexity, and requiring no user interaction. No exploit instructions or confirmed attack campaigns are provided.
Researcher notes
The description claims impact through 3.4.3, but the structured affected record lists version "0" with unknown default status. Confirm scope with current NASA or CVE guidance before declaring individual versions safe. The bundle references updown.py and commands.py, but does not name a patch, fixed commit, public proof of concept, or observed exploitation.
Mitigation direction
Immediately restrict fprime-gds access to trusted management networks and authorized operators.
Disconnect unnecessary spacecraft command links until exposure is assessed.
Check NASA repository, PyPI, and CVE guidance for an official fixed release or mitigation.
Upgrade only according to verified vendor guidance; the supplied sources name no fixed version.
Rotate credentials and secrets accessible from any potentially compromised ground-station host.
Validation and detection
Inventory fprime-gds installations and record exact package versions.
Confirm whether each Flask service is reachable from untrusted networks.
Verify authentication is enforced before all ground-station operations.
Review host and application logs for unexpected uploads, file access, commands, or process execution.
Inspect connected spacecraft command histories for unauthorized or anomalous activity.
After remediation, retest network restrictions and authentication without sending operational spacecraft commands.

Authentication and credential weaknesses can make valid-account abuse and credential telemetry useful review starting points. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
The CVE wording references file access or upload behavior, so file telemetry and web shell review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
