      "value": "Semaphore UI is a web interface for managing DevOps tools. Prior to 2.18.17 and 2.19.5-beta2, repository git_url handling passes an attacker-controlled --upload-pack option to CmdGitClient.GetLastRemoteCommitHash through POST /api/project/{id}/repositories and scheduled commit-hash polling, allowing a project Manager or Owner to execute arbitrary OS commands in the Semaphore server process. This issue is fixed in versions 2.18.17 and 2.19.5-beta2."

Antes de 2.18.17 y 2.19.5-beta2, el manejo de git_url del repositorio pasa una opción --upload-pack controlada por el atacante a CmdGitClient.GetLastRemoteCommitHash a través de POST /API/project/{id}/repositories y el sondeo programado de commit-hash, permitiendo a un Gerente o Propietario de proyecto ejecutar comyos arbitrarios del sistema operativo en el proceso del servidor Semaphore. Este problema está solucionado en las versiones 2.18.17 y 2.19.5-beta2."
