CVE-2026-5967Network attack vector

Root command execution via OS command injection

Published Apr 20, 2026 · Updated Apr 20, 2026

OS command injection in TeamT5 ThreatSonar Anti-Ransomware 4.0.0 and earlier allows remote authenticated users to execute commands as root. The published notices state that the product accepts injected operating-system commands from a user with shell access, but they do not identify the affected command handler or missing neutralization step. Successful exploitation requires authenticated remote shell access and gives the injected commands root privileges, enabling full host compromise.
