Answer in brief
CVE-2026-91163 records a Low severity (CVSS 3.7) vulnerability in Warpgate: Kubernetes listener discloses internal error text to an unauthenticated caller. The current sources do not mark it as known exploited. The current feed maps warp-tech/warpgate (generic). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 3.7. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Warpgate is an open source SSH, HTTPS, and MySQL bastion host for Linux. Prior to 0.29.0, the Kubernetes protocol listener uses AcceptAnyClientCert in warpgate-protocol-kubernetes/src/server/client_certs.rs to accept certificates at the TLS layer and defer validation to warpgate-protocol-kubernetes/src/server/auth.rs, where authentication and lookup failures are rendered verbatim in an HTTP 500 response body. The Kubernetes application in warpgate-protocol-kubernetes/src/server/mod.rs lacks the outer request-logging wrapper used by the HTTP protocol, and failures in warpgate-protocol-kubernetes/src/server/handlers.rs can short-circuit before its inner log point. An unauthenticated network client can therefore induce failures and receive ASN.1/DER parser diagnostics or sea_orm database errors without the attempt being recorded in the gateway log. The disclosed information is limited to internal diagnostics, and no user-data, integrity, or availability impact is established. This issue is fixed in version 0.29.0.
