{"id":"CVE-2026-53451","state":"PUBLISHED","title":"Ground Station: Unauthenticated arbitrary file write (path traversal) in save-waterfall-snapshot leads to remote code execution","description":"Ground Station is a browser-based suite for satellite tracking, SDR reception, hardware control, and telemetry decoding. Prior to version 0.4.13, the unauthenticated save-waterfall-snapshot Socket.IO command passes attacker-controlled snapshotName input from backend/handlers/entities/sdr.py to backend/server/snapshots.py, where os.path.join permits an absolute path or parent-directory traversal and writes attacker-controlled base64-decoded bytes outside backend/data/snapshots. An attacker can write a logging YAML file containing a logging.config.dictConfig callable factory, use the unauthenticated update-app-config operation to set log_config to that file, and invoke restart_service. During restart, backend/common/logger.py passes the YAML through resolve_log_config_path(), yaml.safe_load(), and logging.config.dictConfig(), which executes the factory with service privileges and can also cause a persistent crash loop. This issue is fixed in version 0.4.13.","publishedAt":"2026-08-19T14:45:23.951Z","updatedAt":"2026-08-21T19:32:38.317Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["sgoudelis ground-station"],"affected":[{"vendor":"sgoudelis","product":"ground-station","versions":[{"version":"< 0.4.13","status":"affected"}]}],"references":["https://github.com/sgoudelis/ground-station/security/advisories/GHSA-q35x-w3h6-36w8","https://github.com/sgoudelis/ground-station/commit/5649905f1021155933463a54a76030924adffb9d","https://github.com/sgoudelis/ground-station/releases/tag/v0.4.13"],"weaknesses":["CWE-22","CWE-73","CWE-94"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/53xxx/CVE-2026-53451.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-53451","state":"PUBLISHED","datePublished":"2026-08-19T14:45:23.951Z","dateUpdated":"2026-08-21T19:32:38.317Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-09T16:31:21.494Z"},"containers":{"cna":{"title":"Ground Station: Unauthenticated arbitrary file write (path traversal) in save-waterfall-snapshot leads to remote code execution","descriptions":[{"lang":"en","value":"Ground Station is a browser-based suite for satellite tracking, SDR reception, hardware control, and telemetry decoding.
