  "summary" : "CliInvoke: Argument Injection in Extensibility Runner Factory",
  "details" : "### Impact\nAn argument-injection vulnerability exists in the `CliInvoke`\npackage's runner factory: `RunnerProcessFactory` on the 2.x line and\n`RunnerConfigurationFactory` on the 3.x line.\n\nThe factory joins the runner arguments, the caller's target, and the\ncaller's arguments into a single `ProcessStartInfo.Arguments` string and\nhands it to the OS. The OS command-line parser re-tokenizes the string\nbefore the runner sees it. A double quote (`\"`) in the target or in any\nargument closes the OS-level quoted region and lets the next character\nenter argv as a separate element.\n\n### Patches\nUpgrade to:\n\n- **2.8.5** (2.8.x line)\n- **2.9.4** (2.9.x line)\n- **2.10.5** (2.10.x line)\n- **3.0.0-beta.2** (3.x pre-release line)\n\n### Workarounds\nNo complete workaround is available. Until you can upgrade:\n\n- Strip `\"` from any target or argument before passing it to the\n  factory. On shell runners, also strip `;`, `|`, `&`, `$`, backtick,\n  and parentheses.\n- Or bypass the factory entirely and build the `ProcessConfiguration`\n  directly. Set `ArgumentList` explicitly to the argv you want the\n  runner to receive.\n\nThese are partial mitigations. They shift the quoting problem to your\ncode.",
