Description OSIDB Bzimport 2025-10-08 17:01:18 UTC
HAProxy Kubernetes Ingress Controller before 3.1.13, when the config-snippets feature flag is used, accepts config snippets from users with create/update permissions. This can result in obtaining an ingress token secret as a response. The fixed versions of HAProxy Enterprise Kubernetes Ingress Controller are 3.0.16-ee1, 1.11.13-ee1, and 1.9.15-ee1.
