CVE-2026-67438

OliveTin OS Command Injection via Custom regex: Argument Type Bypassing Shell Safety Check

Published Jul 29, 2026 CVSS 3.1 · 6.6 Medium EPSS 1.6% KEV · Not listed
Description
OliveTin gives access to predefined shell commands from a web interface. From 3000.2.0 until 3000.17.0, the service/internal/executor/arguments.go checkShellArgumentSafety function does not treat regex: custom argument types as unsafe for Shell mode actions, allowing values that pass typeSafetyCheckRegex to be interpolated by wrapCommandInShell into an sh -c command string and enabling OS command injection. This issue is fixed in version 3000.17.0.
