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.","published":"2026-08-19T15:17:10.120","modified":"2026-08-19T15:17:10.120","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/sgoudelis/ground-station/commit/5649905f1021155933463a54a76030924adffb9d","label":"sgoudelis/ground-station@5649905"},"references":[{"type":"WEB","url":"https://github.com/sgoudelis/ground-station/commit/5649905f1021155933463a54a76030924adffb9d"},{"type":"WEB","url":"https://github.com/sgoudelis/ground-station/releases/tag/v0.4.13"},{"type":"WEB","url":"https://github.com/sgoudelis/ground-station/security/advisories/GHSA-q35x-w3h6-36w8"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T15:17:10.120"}}
