CVE-2026-65838 Skipper: an oversized declared-`Content-Length` body still hands OPA an empty `parsed_body`, so deny-on-presence Rego policies fail OPEN while the full payload reaches upstream

Skipper is an HTTP router and reverse proxy for service composition. Prior to 0.27.35, the opaAuthorizeRequestWithBody filter in filters/openpolicyagent/openpolicyagent.go can allow an oversized declared Content-Length request to bypass a deny-on-presence Rego policy because...

CVE-2026-65838

Skipper , an HTTP router and reverse proxy, has a bypass in its OPA authorization filter prior to version 0.27.35 . The opaAuthorizeRequestWithBody filter uses ExtractHttpBodyOptionally, which leaves OPA with an empty parsed_body when an oversized Content-Length request exceeds the -open-policy-a...

Astra Linux – Vulnerability in Waitress

Waitress version 1.3.1 allows for the smuggling of requests by sending the Content-Length header twice. Waitress would fold the two Content-Length headers together, and since it cannot convert the now comma-separated values into integers, it internally sets the Content-Length to 0. If two...

undici: undici: HTTP response splitting via retry interceptor

A flaw was found in undici. An attacker-controlled upstream server can exploit a vulnerability in the retry interceptor, which incorrectly appends data to a ranged retry response. This can cause the response body to be longer than the Content-Length observed by the application. Consequently, an...
