CVE-2026-76221

GitPython before 3.1.58 contains a config-name injection vulnerability in the option-name validator that allows attackers to forge arbitrary git-config directives by injecting equals signs, hash symbols, and whitespace into option names. Attackers can inject malicious option names like 'sshCommand = touch /tmp/RCE #' to execute arbitrary commands via core.sshCommand or core.hooksPath on the next git operation.

Summary		(es) GitPython anterior a la versión 3.1.58 contiene una vulnerabilidad de inyección de nombres de configuración en el validador de nombres de opción que permite a los atacantes forjar directivas git-config arbitrarias inyectando signos de igual, símbolos de almohadilla y espacios en blanco en los nombres de las opciones. Los atacantes pueden inyectar nombres de opción maliciosos como ’sshCommand = touch /tmp/RCE #’ para ejecutar comandos arbitrarios a través de core.sshCommand o core.hooksPath en la siguiente operación de git.
