      "value": "Repomix is a tool that packs repositories into AI-friendly files. Prior to 1.14.1, src/core/git/gitCommand.ts execGitShallowClone passes the --remote-branch value directly to git fetch and git checkout without validation or --end-of-options, allowing --upload-pack or other Git option injection that bypasses validateGitUrl() dangerous parameter checks and can execute commands through local or SSH-style transports. This issue is fixed in version 1.14.1."

Antes de la versión 1.14.1, src/core/git/gitCommand.ts execGitShallowClone pasa el valor de --remote-branch directamente a git fetch y git checkout sin validación o --end-of-options, permitiendo la inyección de --upload-pack u otra opción de Git que omite las comprobaciones de parámetros peligrosos de validateGitUrl() y puede ejecutar comandos a través de transportes locales o de estilo SSH. Este problema se ha solucionado en la versión 1.14.1."
