CVE-2026-67438: Olivetin

Medium severity, CVSS 6.6. EPSS: 1.6% chance of exploitation in the next 30 days.

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.

Affected products

• Olivetin Olivetin: from 3000.2.0, before 3000.17.0 (fixed in 3000.17.0)
