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.","published":"2026-09-11T15:17:08.357","modified":"2026-09-11T15:17:08.357","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://docs.wavlink.xyz/"},{"type":"WEB","url":"https://github.com/camdsmith/wavlink-sync_server-rce/blob/main/README.md"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/wavlink-wn535m1-wn535m3-unauthenticated-os-command-injection-via-sync-server"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T15:17:08.357"}}
