The vulnerability allows sending an unencrypted data frame to a WPA2-protected WLAN router where the packet is routed through the network. If successful, a response is sent back as an encrypted frame, which would allow an attacker to discern information or potentially modify data.","published":"2020-09-30T18:15:17.000Z","lastModified":"2026-06-17T02:25:43.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"cwe":["CWE-290"],"affected":["realtek/rtl8812ar firmware","realtek/rtl8196d firmware","realtek/rtl8192er firmware","realtek/rtl8881an firmware"],"epss":{"score":0.00751,"percentile":0.54696,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.75%).
