{"id":"CVE-2026-111623","summary":"Xiaozhi-esp32-server-java through 6.1.0 Authentication Bypass via OTA Endpoint Token Issuance","details":"Xiaozhi-esp32-server-java through 6.1.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to obtain valid device WebSocket tokens by requesting /api/device/ota with any MAC address. Attackers can open a victim device's WebSocket channel to read private role system prompts, write conversation history, consume LLM/STT/TTS credentials, and overwrite device metadata.","modified":"2026-10-21T02:55:12.045593098Z","published":"2026-10-16T17:38:59.425Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-290"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111623.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111623.json"},{"type":"PACKAGE","url":"https://github.com/joey-zhou/xiaozhi-esp32-server-java"},{"type":"ARTICLE","url":"https://github.com/joey-zhou/xiaozhi-esp32-server-java/blob/v6.1.0/xiaozhi-common/src/main/java/com/xiaozhi/communication/auth/DeviceAuthService.java#L76-L81"},{"type":"ARTICLE","url":"https://github.com/joey-zhou/xiaozhi-esp32-server-java/blob/v6.1.0/xiaozhi-server/src/main/java/com/xiaozhi/device/DeviceAppService.java#L298-L346"},{"type":"ARTICLE","url":"https://github.com/joey-zhou/xiaozhi-esp32-server-java/blob/v6.1.0/xiaozhi-server/src/main/java/com/xiaozhi/device/DeviceController.java#L142-L153"},{"type":"ADVISORY","url":"https://hackmd.io/@hieuPenguinnn/xiaozhi-esp32-server-java-ota-device-token-issuance"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111623"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/xiaozhi-esp32-server-java-through-6.1.0-authentication-bypass-via-ota-endpoint-token-issuance"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/joey-zhou/xiaozhi-esp32-server-java","events":[{"introduced":"0"},{"last_affected":"90d24e49d09dda19865b134c387cc1bfd30f9a10"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"last_affected":"6.1.0"}]}]}}],"versions":["v6.1.0","v5.1.0","v5.0.0","v4.1.0","v4.0.0","v3.0.0","v2.8.18","v2.8.17","v2.8.14","v2.8.13","v2.8.12","v2.8.11","v2.8.10","v2.8.9","v2.8.7","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8.0","v2.7.65","v2.7.64","v2.7.62","v2.7.61","v2.7.60","v2.7.57"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111623.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
