CVE-2026-50197

Skipper is an HTTP router and reverse proxy for service composition. Prior to 0.26.10, zalando/skipper's OpenPolicyAgent integration silently bypasses request-body inspection on HTTP/1.1 Transfer-Encoding: chunked and HTTP/2 requests that omit the content-length pseudo-header, because the opaAuthorizeRequestWithBody filter and OpenPolicyAgentInstance.ExtractHttpBodyOptionally in filters/openpolicyagent/openpolicyagent.go produce an empty raw_body and input.parsed_body while the upstream service receives the full attacker-controlled body. This issue is fixed in version 0.26.10.

Summary		(es) Skipper es un router HTTP y proxy inverso para composición de servicios. Antes de la versión 0.26.10, la integración de OpenPolicyAgent de zalando/skipper omite silenciosamente la inspección del cuerpo de la solicitud en solicitudes HTTP/1.1 con Transfer-Encoding: chunked y solicitudes HTTP/2 que omiten el pseudo-encabezado content-length, porque el filtro opaAuthorizeRequestWithBody y OpenPolicyAgentInstance.ExtractHttpBodyOptionally en filters/openpolicyagent/openpolicyagent.go producen un raw_body y un input.parsed_body vacíos mientras que el servicio ascendente recibe el cuerpo completo controlado por el atacante. Este problema está solucionado en la versión 0.26.10.
