{"apiVersion":"1.0","identifier":"CVE-2026-53451","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":"2026-08-19T15:17:10","lastModifiedAt":"2026-08-21T20:16:36","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53451","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00725,"riskScore":1.04,"affectedProduct":"Ground Station","affectedVersions":"<0.4.13","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53451","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53451","en":"https://www.redsauce.net/en/cves/CVE-2026-53451","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53451","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53451","de":"https://www.redsauce.net/de/cves/CVE-2026-53451","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53451","el":"https://www.redsauce.net/el/cves/CVE-2026-53451"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53451"}}
