| CVE-2026-41246 | Contour is a Kubernetes ingress controller using Envoy proxy. From v1.19.0 to before v1.33.4, v1.32.5, and v1.31.6, Contour's Cookie Rewriting feature is vulnerable to Lua code injection. An attacker with RBAC permissions to create or modify HTTPProxy resources can craft a malicious value in spec.routes[].cookieRewritePolicies[].pathRewrite.value or spec.routes[].services[].cookieRewritePolicies[].pathRewrite.value that results in arbitrary code execution in the Envoy proxy. The cookie rewriting | [email protected] | 8.1 | 0.48% | 2026-04-23 | 2026-06-29 |
| CVE-2024-36539 | Insecure permissions in contour v1.28.3 allows attackers to access sensitive data and escalate privileges by obtaining the service account's token. | [email protected] | 9.8 | 1.26% | 2024-07-24 | 2026-06-17 |
| CVE-2023-44487 KEV | The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | [email protected] | 7.5 | 100.00% | 2023-10-10 | 2026-06-17 |
| CVE-2021-32783 | Contour is a Kubernetes ingress controller using Envoy proxy. In Contour before version 1.17.1 a specially crafted ExternalName type Service may be used to access Envoy's admin interface, which Contour normally prevents from access outside the Envoy container. This can be used to shut down Envoy remotely (a denial of service), or to expose the existence of any Secret that Envoy is using for its configuration, including most notably TLS Keypairs. However, it *cannot* be used to get the *content* | [email protected] | 8.5 | 1.15% | 2021-07-23 | 2026-06-16 |
| CVE-2020-15127 | In Contour ( Ingress controller for Kubernetes) before version 1.7.0, a bad actor can shut down all instances of Envoy, essentially killing the entire ingress data plane. GET requests to /shutdown on port 8090 of the Envoy pod initiate Envoy's shutdown procedure. The shutdown procedure includes flipping the readiness endpoint to false, which removes Envoy from the routing pool. When running Envoy (For example on the host network, pod spec hostNetwork=true), the shutdown manager's endpoint is acc | [email protected] | 7.5 | 1.38% | 2020-08-05 | 2026-06-16 |
