CVE-2026-49445 Cilium: Sensitive information disclosure and cluster disruption via local Envoy admin socket access

Cilium is a networking, observability, and security solution. Prior to 1.17.14, 1.18.8, and 1.19.2, when Cilium L7 functionality is enabled, the embedded or standalone Envoy instance creates a world-accessible admin.sock on cluster nodes, allowing a local attacker to access Envoy admin endpoints,...

CVE-2026-12382

A flaw was found in the AAP Gateway Envoy proxy configuration. The non-mTLS route to EDA event streams does not remove the Subject HTTP header from client requests, despite the source code defining requestHeadersToRemove for this header. An unauthenticated remote attacker can inject a spoofed...

GO-2026-5905 Cilium vulnerable to sensitive information disclosure and cluster disruption via local Envoy admin socket access in github.com/cilium/cilium

Cilium vulnerable to sensitive information disclosure and cluster disruption via local Envoy admin socket access in github.com/cilium/cilium...

Improper Access Control

Cilium is vulnerable to improper access control. The vulnerability is due to the creation of a world-accessible Envoy admin socket when L7 functionality is enabled, which allows a local attacker to access Envoy administrative endpoints, potentially exposing sensitive information such as TLS...

Cilium vulnerable to sensitive information disclosure and cluster disruption via local Envoy admin socket access

Impact When Cilium L7 functionality is enabled on a cluster, the Envoy instance supporting this functionality creates a world-accessible socket on cluster nodes. A local attacker would be able to access Envoy admin endpoints. Depending on deployment configuration, this can expose sensitive...

Missing Authorization

Overview Affected versions of this package are vulnerable to Missing Authorization via the Envoy admin socket when L7 functionality is enabled. An attacker can access sensitive information or disrupt cluster operations by connecting to the world-accessible socket and invoking administrative...

GHSA-3FCV-JVFP-M4Q9 Cilium vulnerable to sensitive information disclosure and cluster disruption via local Envoy admin socket access

Impact When Cilium L7 functionality is enabled on a cluster, the Envoy instance supporting this functionality creates a world-accessible socket on cluster nodes. A local attacker would be able to access Envoy admin endpoints. Depending on deployment configuration, this can expose sensitive...

PT-2026-56051

Name of the Vulnerable Software and Affected Versions Cilium versions 1.19.0 through 1.19.1 Cilium versions 1.18.0 through 1.18.7 Cilium versions prior to 1.17.14 Description When L7 functionality is enabled, the Envoy instance creates a world-accessible socket on cluster nodes. A local attacker...

CVE-2026-47692

A flaw was found in Envoy. The PROXY Protocol v2 header generator can emit data beyond the maximum allowed length, leading to a mismatch between the actual bytes sent and the length specified in the header. An attacker on an adjacent network could exploit this to smuggle bytes into upstream...

CVE-2026-47221

A flaw was found in Envoy. An unauthenticated attacker can exploit a null pointer dereference vulnerability in the router filter. This occurs when handling HTTP 303 See Other internal redirects for body-less non-GET/HEAD requests. By sending a POST, PUT, DELETE, or PATCH request without a body to...

CVE-2026-48743

A flaw was found in Envoy, an open source edge and service proxy. This vulnerability occurs when Envoy translates an HTTP/3 request that is complete at the transport layer but still carries a nonzero Content-Length into an HTTP/1 request for an upstream server. If the upstream server responds...

CVE-2026-48044

A flaw was found in Envoy, an open source edge and service proxy. A remote attacker can exploit this vulnerability by sending a specially crafted, highly compressed zstd payload to an Envoy proxy with zstd decompression enabled. This can lead to massive memory allocation, causing severe memory...

CVE-2026-48042

A flaw was found in Envoy, an open-source edge and service proxy. A remote attacker could exploit this vulnerability by sending deeply nested JSON objects to the affected system. This could lead to a stack overflow during the destruction of JSON objects, resulting in a Denial of Service DoS for t...

CVE-2026-47204

A flaw was found in Envoy, an open source edge and service proxy. A remote attacker can exploit this vulnerability by sending a specially crafted Connect protocol request to a direct response route.
