El complemento de autenticación de Jenkins OpenId Connect 4.452.v2849b_d3945fa_ y anteriores, excepto 4.438.440.v3f5f201de5dc, trata los nombres de usuario como si no distinguieran entre mayúsculas y minúsculas, lo que permite a los atacantes en instancias de Jenkins configuradas con un proveedor de OpenID Connect que distinga entre mayúsculas y minúsculas iniciar sesión como cualquier usuario al proporcionar un nombre de usuario que difiere solo en mayúsculas y minúsculas, lo que potencialmente les permite obtener acceso de administrador a Jenkins.
