CVE-2026-2956Public exploitNetwork attack vector

Authenticated command injection via crafted backup name

Published Feb 22, 2026 · Updated Feb 22, 2026

Command injection in qinming99 dst-admin 1.5.0 and earlier allows remote authenticated users to execute system commands via a crafted backup name. The /home/restore revertBackup handler incorporates the attacker-controlled Name argument into an operating-system command without neutralizing command separators. Low-privileged application access is required, and injected commands run with the privileges of the dst-admin process.
