CVE-2026-59864

Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.29.1 and 1.32.5, `kiota plugin add` and `kiota plugin generate` (with `-t APIPlugin`) emitted attacker-controlled static_template.file values from x-ai-adaptive-card and x-ai-capabilities into generated Microsoft 365 Copilot and Teams plugin manifests without path validation, allowing ../, absolute, rooted, UNC, Windows drive, or URI paths in response_semantics.static_template.file to cause path traversal or out-of-package file inclusion when the generated plugin was deployed. This issue is fixed in version 1.29.1 and 1.32.5.

Summary		(es) Kiota es un generador de código de cliente HTTP basado en OpenAPI. Antes de la versión 1.32.5, “kiota plugin add” y “kiota plugin generate” (con “-t APIPlugin”) emitían valores de static_template.file controlados por el atacante desde x-ai-adaptive-card y x-ai-capabilities en los manifiestos de plugin generados de Microsoft 365 Copilot y Teams sin validación de ruta, permitiendo que rutas .. / , absolutas, raíz, UNC, de unidad de Windows o URI en response_semantics.static_template.file causaran salto de ruta o inclusión de ficheros fuera del paquete cuando el plugin generado era desplegado. Este problema está solucionado en la versión 1.32.5.
