The weakness stems from inadequate validation of user\u2011supplied file paths, a classic CWE\u201122 scenario. The impact is the potential compromise of confidentiality for any files the attacker can traverse to, such as configuration or sensitive documents, without affecting integrity or availability directly.", "risk_and_exploitability": "The CVSS score of 1.3 reflects the low impact and the requirement that the attacker must already have legitimate user credentials or a compromised account. The EPSS score of less than 1% indicates a very low probability of exploitation in the wild, and the vulnerability is not reported as a known exploited threat in CISA\u2019s KEV catalog. The attack would involve authenticating to the system first and then manipulating file paths to read unintended files, a process that does not require additional privileges beyond those granted to the user account."}}}}, "created": "2026-02-11T21:45:36.767631+00:00", "title": "Path Traversal Allows Unauthorized System File Disclosure in QNAP File Station 5", "updated": "2026-04-17T20:30:15.810799+00:00", "vendors": ["qnap_systems", "qnap_systems$PRODUCT$file_station_5"]}
