An unauthenticated attacker can connect to the\n OCPP WebSocket endpoint using a known or discovered charging station \nidentifier, then issue or receive OCPP commands as a legitimate charger.\n Given that no authentication is required, this can lead to privilege \nescalation, unauthorized control of charging infrastructure, and \ncorruption of charging network data reported to the backend.","published":"2026-02-27T00:16:58.000Z","lastModified":"2026-06-17T10:25:20.000Z","status":"Modified","sourceIdentifier":"ics-cert@hq.dhs.gov","cvss":{"version":"4.0","score":9.3,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/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/M"},"cwe":["CWE-306"],"affected":["chargemap/chargemap.com"],"epss":{"score":0.00747,"percentile":0.54647,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.75%).
