CVE-2026-72577 · Severity: critical · CVSS 9.8 · Published 2026-08-10

NASA's F´ Ground Data System (fprime-gds) is software used to command and monitor spacecraft. Versions through 3.4.3 contain multiple vulnerabilities that allow an attacker on the network to execute arbitrary code on the ground station computer and inject commands into connected spacecraft, with no authentication required. This could result in loss of mission control, data compromise, or unauthorized spacecraft manipulation.

Vendors: [Nasa](https://junglewise.ai/threats/vendors/nasa).

**How is CVE-2026-72577 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-72577?** Check whether you run Nasa Fprime-Gds at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## Technical details

The Flask web application in fprime-gds through version 3.4.3 lacks authentication on all endpoints, allowing unauthenticated remote access. The vulnerabilities enable arbitrary code execution on the ground station host and injection of arbitrary commands to connected spacecraft. The root cause is the absence of authentication controls in src/fprime_gds/flask/app.py. An attacker with network access to the Flask application can exploit these endpoints without credentials. The attack vector is network-based and requires no user interaction or prior access. Patch availability and mitigation details should be obtained from NASA or the official fprime-gds repository.
