GHSA-fp9f-44c2-cw27Ingress-nginx code injection via nginx.ingress.kubernetes.io/permanent-redirect annotation2023-10-25ghsa · osvUS
A security issue was identified in [ingress-nginx](https://github.com/kubernetes/ingress-nginx) where the nginx.ingress.kubernetes.io/permanent-redirect annotation on an Ingress object (in the networking.k8s.io or extensions API group) can be used to inject arbitrary commands, and obtain the credentials of the ingress-nginx controller. In the default configuration, that credential has access to all secrets in the cluster.

Ingress-nginx code injection via nginx.ingress.kubernetes.io/permanent-redirect annotation in k8s.io/ingress-nginx. NOTE: The source advisory for this report contains additional versions that could not be automatically mapped to standard Go module versions. (If this is causing false-positive reports from vulnerability scanners, please suggest an edit to the report.) The additional affected modules and versions are: k8s.io/ingress-nginx before v1.9.0.
