CVE-2026-39054Network attack vector

Command execution via unsanitized shell input

Published May 15, 2026 · Updated May 15, 2026

OS command injection in Oinone Pamirs 7.0.0 allows remote attackers to execute arbitrary commands through application paths that invoke the helper. CommandHelper.executeCommands starts a shell process and writes each supplied command string directly to standard input without sanitization, allowlisting, or argument separation. Reachability requires an application feature, extension, or plugin to pass untrusted input into the helper; successful exploitation runs commands with service privileges.
