Kiota: Generation-time SSRF + remote/local file inclusion via unrestricted $ref

EPSS Percentile
0th
Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.32.5, Kiota resolved OpenAPI $ref values by fetching remote http(s) URLs and reading local absolute or out-of-tree file paths, allowing `kiota generate` on an attacker-controlled or attacker-influenced description to perform build-time SSRF, remote file inclusion, and local file inclusion by inlining external schemas such as REMOTE_KIOTA_PROP or Leaked into generated clients. This issue is fixed in version 1.32.5 by AllowedExternalOriginsStreamLoader and the --allowed-external-origins option.
