This improper privilege handling enables the user to execute actions with administrator\u2011level access, effectively leaking administrative privileges to an otherwise non\u2011privileged user. The vulnerability is a classic example of CWE\u2011269, where privileged operations are performed by a process that may be exploited by a local adversary to compromise the confidentiality, integrity, and availability of the system.", "risk_and_exploitability": "The vulnerability carries a CVSS score of 8.8, indicating high severity, and no EPSS score is provided, meaning its exploitation probability has not been quantified. It is not listed in CISA's KEV catalog. Based on the description, the likely attack vector is local, requiring the attacker to run the application and manipulate the file selection dialog. Once triggered, the elevated privileges granted by the application allow the attacker to perform arbitrary privileged actions without additional authentication."}}}}, "created": "2026-04-28T09:17:27.241181+00:00", "title": "Local Privilege Escalation via Improper Path Handling in Fan Control Open File Dialog", "updated": "2026-04-28T13:15:31.888884+00:00", "vendors": ["rem0o", "rem0o$PRODUCT$fan_control"]}
