CVE-2026-53452
MediumCVSS 5.3Summary
Ground Station prior to version 0.4.13 contains a vulnerability where the unauthenticated configure-sdr Socket.IO command accepts a recordingPath for the sigmf-playback SDR and stores it without validation before opening the path without enforcing containment. An absolute path or parent-directory escape ending in .sigmf-meta is parsed as JSON and returned in reply["data"]["metadata"] by the get-sdr-parameters flow. Exploitation requires the metadata file to be readable JSON and to have a sibling .sigmf-data file, but it can disclose contents outside backend/data/recordings without authentication.
Risk Assessment
An unauthenticated attacker can read sensitive files from the system, potentially leading to data disclosure or further attacks.
Recommendation
Update Ground Station to version 0.4.13 or later, which includes fixes for the vulnerability. Additionally, enforce path validation and file access restrictions.
Original NVD description (English source)
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 configure-sdr Socket.IO command accepts a recordingPath for the sigmf-playback SDR and backend/handlers/entities/sdr.py stores it without validation before backend/hardware/sigmfprobe.py opens the path without enforcing containment. An absolute path or parent-directory escape ending in .sigmf-meta is parsed as JSON and returned in reply["data"]["metadata"] by the get-sdr-parameters flow. Exploitation requires the metadata file to be readable JSON and to have a sibling .sigmf-data file, but it can disclose contents outside backend/data/recordings without authentication. This issue is fixed in version 0.4.13.
