The daemon interpolates attacker-controlled filename input containing shell metacharacters into a shell command string via sprintf() and passes it to system() without sanitization, enabling root-level command execution on the device.","state":0,"publishedAt":"2026-09-11T14:57:56.223+00:00","modifiedAt":"2026-10-29T17:46:46.349+00:00","affected":[{"ecosystem":"Vendor product","name":"WN535M1","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"WAVLINK Technology\",\n                    \"product\": \"WN535M1\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"M35M1_V210223\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"M35M1_V250922\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"WN535M3","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"WAVLINK Technology\",\n                    \"product\": \"WN535M3\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"M35M1_V210223\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"M35M1_V250922\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/camdsmith/wavlink-sync_server-rce/blob/main/README.md","https://docs.wavlink.xyz/Security_Advisory/WAVLINK-SA-2026-091302/","https://www.vulncheck.com/advisories/wavlink-wn535m1-wn535m3-unauthenticated-os-command-injection-via-sync-server"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89010","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89010","identifiers":["CVE-2026-89010"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
