CVE-2026-100369
CliInvoke and its formerly named `AlastairLundy.CliInvoke` package are .NET libraries for invoking command-line programs and wrapping executable processes. `CliInvoke` versions 2.0.0 through 2.8.4, 2.9.0 through 2.9.3, 2.10.0 through 2.10.4, and 3.0.0-alpha.1 through 3.0.0-beta.1, as well as `AlastairLundy.CliInvoke` versions 2.0.0-alpha.1 through 2.0.0, contain an argument-injection vulnerability in `RunnerProcessFactory` on the 2.x line and `RunnerConfigurationFactory` on the 3.x line. These factories combine runner arguments, a caller-controlled target, and caller-controlled arguments into one `ProcessStartInfo.Arguments` string, allowing a double quote in the target or an argument to terminate an operating-system-level quoted region and inject unintended elements into the runner’s argument vector, potentially resulting in arbitrary command execution when a shell runner is used. The vulnerability is patched in `CliInvoke` versions 2.8.5, 2.9.4, 2.10.5, and 3.0.0-beta.2, and in `AlastairLundy.CliInvoke` version 2.0.2. No complete workaround is available; users unable to upgrade can partially mitigate the issue by removing double quotes from targets and arguments, additionally rem
