Title
Skipper Incomplete Fix for CVE-2026-50197 Policy Bypass
Summary
Skipper contains an incomplete fix for CVE-2026-50197 in which oversized request bodies bypass Open Policy Agent (OPA) deny-on-presence Rego policies. When a request body exceeds the configured maxBodyBytes limit, Skipper forwards the full payload to the upstream service while OPA evaluates against an empty parsed_body, so policies that deny requests based on body content are not enforced and forbidden actions proceed. No fixed version is available; v0.27.26 adds documentation guidance only.
