{"id":"CVE-2026-53983","state":"PUBLISHED","title":"Ground Station prior to 0.6.0 Unauthenticated Persistent Blind Server-Side Request Forgery via Orbital Data Source URL","description":"Ground Station prior to 0.6.0 contains an unauthenticated blind server-side request forgery vulnerability in the orbital-source configuration path that allows any unauthenticated Socket.IO client to cause the ground-station process to issue outbound HTTP requests to attacker-chosen destinations. Attackers can connect to the Socket.IO server on port 7000 without credentials due to disabled authentication enforcement and a wildcard CORS policy, then submit a data_submission event with submit-orbital-sources action to persist an attacker-supplied URL in the database, then trigger an orbital sync via the equally unauthenticated background_task:start event. The URL is stored with no scheme allowlist, no host validation, and no rejection of loopback, RFC1918, or link-local (cloud instance metadata at 169.254.169.254) addresses, and is passed directly to requests.get in _fetch_http_3le and _fetch_http_omm in backend/tlesync/source_adapters.py. HTTP status codes and error messages from the outbound request are emitted in the orbital_sync_state Socket.IO event to all connected clients, providing a serviceable oracle for interpreting internal-service and cloud-metadata responses even though the raw response body is not directly leaked. Because the malicious source persists in the database across restarts and re-fires every 24 hours on the scheduled sync cycle, the primitive gives durable long-term SSRF without the attacker needing to remain connected.","publishedAt":"2026-08-06T15:38:02.143Z","updatedAt":"2026-08-07T15:18:37.153Z","severity":{"score":9.2,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["Efstratios Goudelis Ground Station"],"affected":[{"vendor":"Efstratios Goudelis","product":"Ground Station","defaultStatus":"affected","versions":[{"version":"0","status":"affected","lessThan":"0.6.0","versionType":"semver"}]}],"references":["https://github.com/sgoudelis/ground-station","https://github.com/sgoudelis/ground-station/security/advisories/GHSA-mjp8-x6h7-229q","https://github.com/sgoudelis/ground-station/commit/2ecde82a8814cbea18883ce023bf45cbf06172eb"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/53xxx/CVE-2026-53983.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-53983","state":"PUBLISHED","datePublished":"2026-08-06T15:38:02.143Z","dateUpdated":"2026-08-07T15:18:37.153Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-06-11T16:07:13.000Z"},"containers":{"cna":{"title":"Ground Station prior to 0.6.0 Unauthenticated Persistent Blind Server-Side Request Forgery via Orbital Data Source URL","descriptions":[{"lang":"en","value":"Ground Station prior to 0.6.0 contains an unauthenticated blind server-side request forgery vulnerability in the orbital-source configuration path that allows any unauthenticated Socket.IO client to cause the ground-station process to issue outbound HTTP requests to attacker-chosen destinations.
