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.","state":0,"publishedAt":"2026-07-17T19:23:43.574+00:00","modifiedAt":"2026-07-20T14:33:29.442+00:00","affected":[{"ecosystem":"Vendor product","name":"skipper","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"zalando\",\n                    \"product\": \"skipper\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.26.10\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","score":7.8,"severity":"HIGH"}],"references":["https://github.com/zalando/skipper/security/advisories/GHSA-659f-rgp5-w4wf","https://github.com/zalando/skipper/pull/4041","https://github.com/zalando/skipper/commit/3152f3b0bb52ca89c3564be42434db0a2a1cea23","https://github.com/zalando/skipper/releases/tag/v0.26.10"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-50197","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-50197","identifiers":["CVE-2026-50197"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
