The affected application does not sufficiently restrict the permissions assigned to a database role.\nThis could allow an authenticated remote attacker with database access to escalate privileges and execute arbitrary commands on the host system where SIMATIC WinCC is installed, potentially leading to a compromise of the system.","dates":{"published":"2026-10-13T09:18:29.536Z","modified":"2026-10-16T17:18:25.910Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.8,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00499,"percentile":0.41504,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-14T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00499,"percentile":0.41504}],"last30":[{"date":"2026-10-14T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00499,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00499,"percentile":0.41504}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-266","name":"Incorrect
