CVE-2026-100369 — CliInvoke: Argument Injection in CliInvoke — CVE...

### Impact An argument-injection vulnerability exists in the `CliInvoke` package's runner factory: `RunnerProcessFactory` on the 2.x line and `RunnerConfigurationFactory` on the 3.x line. The factory joins the runner arguments, the caller's target, and the caller's arguments into a single `ProcessStartInfo.Arguments` string and hands it to the OS. The OS command-line parser re-tokenizes the string before the runner sees it. A double quote (`"`) in the target or in any argument closes the OS-level quoted region and lets the next character enter argv as a separate element. ### Patches Upgrade to: - **2.8.5** (2.8.x line) - **2.9.4** (2.9.x line) - **2.10.5** (2.10.x line) - **3.0.0-beta.2** (3.x pre-release line) ### Workarounds No complete workaround is available. Until you can upgrade: - Strip `"` from any target or argument before passing it to the factory. On shell runners, also strip `;`, `|`, `&`, `$`, backtick, and parentheses. - Or bypass the factory entirely and build the `ProcessConfiguration` directly. Set `ArgumentList` explicitly to the argv you want the runner to receive. These are partial mitigations. They shift the quoting problem to your code.
