A local low-privileged attacker can replace rollback backup files stored in a user-writable temporary directory before they are restored by an elevated installer, resulting in privilege escalation to NT AUHORITY/SYSTEM. Exploitation requires successful timing of the race condition and a rollback during installation or update.","state":0,"publishedAt":"2026-09-29T15:39:53.082+00:00","modifiedAt":"2026-09-30T15:28:19.1+00:00","affected":[{"ecosystem":"Vendor product","name":"Full Client","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"TeamViewer\",\n                    \"product\": \"Full Client\",\n                    \"platforms\": [\n                        \"Windows\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"15.0\",\n                            \"lessThan\": \"15.82\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"15.64.0 (Legacy Windows 7 & 8)\",\n                            \"lessThan\": \"15.64.8 (Legacy Windows 7 & 8)\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"14.7.0\",\n                            \"lessThan\": \"14.7.48855\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"13.2.0\",\n                            \"lessThan\": \"13.2.36230\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"Host","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"TeamViewer\",\n                    \"product\": \"Host\",\n                    \"platforms\": [\n                        \"Windows\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"15.0\",\n                            \"lessThan\": \"15.82\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"15.64.0 (Legacy Windows 7 & 8)\",\n                            \"lessThan\": \"15.64.8 (Legacy Windows 7 & 8)\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"14.7.0\",\n                            \"lessThan\": \"14.7.48855\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"13.2.0\",\n                            \"lessThan\": \"13.2.36230\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","score":7.3,"severity":"HIGH"}],"references":["https://www.teamviewer.com/en/resources/trust-center/security-bulletins/tv-2026-1010/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92369","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92369","identifiers":["CVE-2026-92369"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
