{"id":"CVE-2026-53983","summary":"Ground Station prior to 0.6.0 Unauthenticated Persistent Blind Server-Side Request Forgery via Orbital Data Source URL","details":"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.","aliases":["CVE-2026-53984","CVE-2026-53985","GHSA-mjp8-x6h7-229q"],"modified":"2026-08-07T11:56:10.889291381Z","published":"2026-08-06T15:38:02.143Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53983.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53983.json"},{"type":"PACKAGE","url":"https://github.com/sgoudelis/ground-station"},{"type":"FIX","url":"https://github.com/sgoudelis/ground-station/commit/2ecde82a8814cbea18883ce023bf45cbf06172eb"},{"type":"ADVISORY","url":"https://github.com/sgoudelis/ground-station/security/advisories/GHSA-mjp8-x6h7-229q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53983"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sgoudelis/ground-station","events":[{"introduced":"0"},{"fixed":"2ecde82a8814cbea18883ce023bf45cbf06172eb"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"0.6.0"}]}}],"versions":["v0.5.2","v0.5.1","v0.5.0","v0.4.13","v0.4.12","v0.4.11","v0.4.10","v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.16","v0.3.15","v0.3.14","v0.3.13","v0.3.12","v0.3.11","v0.3.10","v0.3.9","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.19","v0.2.18","v0.2.17","v0.2.16","v0.2.15","v0.2.14","v0.2.13","v0.2.11","v0.2.10","v0.2.9","v0.2.8","v0.2.7","v0.2.6","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.85","v0.1.84","v0.1.83","v0.1.82","v0.1.81","v0.1.80","v0.1.79","v0.1.78","v0.1.77","v0.1.76","v0.1.75","v0.1.74","v0.1.73","v0.1.72","v0.1.71","v0.1.70","v0.1.69","v0.1.68","v0.1.67","v0.1.66","v0.1.65","v0.1.64","v0.1.63","v0.1.62","v0.1.61","v0.1.60","v0.1.59","v0.1.58","v0.1.57","v0.1.56","v0.1.55","v0.1.54","v0.1.53","v0.1.52","v0.1.51","v0.1.50","v0.1.49","v0.1.48","v0.1.47","v0.1.46","v0.1.45","v0.1.44","v0.1.43","v0.1.42","v0.1.41","v0.1.40","v0.1.39","v0.1.38","v0.1.37","v0.1.36","v0.1.35","v0.1.34","v0.1.33","v0.1.32","v0.1.31","v0.1.30","v0.1.29","v0.1.28","v0.1.27","v0.1.26","v0.1.25","v0.1.24","v0.1.23","v0.1.22","v0.1.21","v0.1.20","v0.1.19","v0.1.18","v0.1.17","v0.1.16","v0.1.15","v0.1.14","v0.1.13","v0.1.12","v0.1.11","v0.1.10","v0.1.9","v0.1.8","v0.1.7","0.1.7","v0.1.6","v0.1.5-test6","v0.1.5-test5","v0.1.5-test4","v0.1.5-test3","v0.1.5-test2","v0.1.5-test1","v0.1.5","push","v0.1.4","v0.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53983.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"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"}]}
