A privileged local attacker can craft a shortcut that points to an arbitrary path, causing the system to create a file with system privileges. This can be leveraged to write malicious binaries or configuration files that persist with elevated privileges, potentially enabling further code execution or persistence on the device.", "risk_and_exploitability": "The CVSS score for this weakness is 6.8, indicating moderate severity. The EPSS score is reported as less than 1\u202f%, suggesting that exploitation is currently unlikely, and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires a local privilege, meaning the attacker must already have privileged access to the device or be a local user with sufficient rights to create shortcuts. Despite the low exploitation probability, the impact remains significant due to the potential for persistent privilege escalation."}}}}, "created": "2026-02-04T21:18:15.083005+00:00", "title": "Path Traversal in Android ShortcutService Allows File Creation with System Privileges", "updated": "2026-04-18T18:45:05.746555+00:00", "vendors": ["samsung", "samsung$PRODUCT$mobile_devices"]}
