Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

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.
