### Impact Gateway API HTTPRoutes and GRPCRoutes do not follow the match precedence specified in the Gateway API specification. In particular, request headers are matched before request methods, when the specification describes that the request methods must be respected before headers are matched ([HTTPRouteRule](https://gateway-api.sigs.k8s.io/reference/spec/#gateway.networking.k8s.io/v1.HTTPRouteRule), [GRPCRouteRule](https://gateway-api.sigs.k8s.io/reference/spec/#gateway.networking.k8s.io%2fv1.GRPCRouteRule)). If users create Gateway API resources that use both request headers and request methods in order to route to different destinations, then traffic may be delivered to the incorrect backend. If the backend does not have Network Policy restricting acceptable traffic to receive, then requests may access information that you did not intend for them to access. ### Patches This issue was fixed in https://github.com/cilium/cilium/pull/34109. This issue affects: - Cilium v1.15 be...

### Summary _Using an "open at the top" range definition in RBAC for etcd roles leads to some TCPs API servers being able to read, write and delete the data of other control planes._ ### Details The problematic code is this: https://github.com/clastix/kamaji/blob/8cdc6191242f80d120c46b166e2102d27568225a/internal/datastore/etcd.go#L19-L24 The range created by this RBAC setup code looks like this: ``` etcdctl role get example Role example KV Read: [/example/, \0) KV Write: [/example/, \0) ``` The range end `\0` means "everything that comes after" in etcd, so potentially all the key prefixes of controlplanes with a name that comes after "example" when sorting lexically (e.g. `example1`, `examplf`, all the way to `zzzzzzz` if you will). ### PoC 1. Create two TCP in the same Namespace 2. Scale Kamaji to zero to avoid reconciliations 3. change the Kubernetes API Server `--etcd-prefix` flag value to point to the other TCP datastore key 4. wait it for get it up and running 5. use `ku...

Cybersecurity startup RAD Security, a finalist in this year's Black Hat USA Startup Spotlight competition, looks for "drift events," or events that vary from the baseline.

Meshery is an open source, cloud native manager that enables the design and management of Kubernetes-based infrastructure and applications. A SQL injection vulnerability in Meshery prior to version 0.7.22 may lead to arbitrary file write by using a SQL injection stacked queries payload, and the ATTACH DATABASE command. Additionally, attackers may be able to access and modify any data stored in the database, like performance profiles (which may contain session cookies), Meshery application data, or any Kubernetes configuration added to the system. The Meshery project exposes the function `GetAllEvents` at the API URL `/api/v2/events`. The sort query parameter read in `events_streamer.go` is directly used to build a SQL query in `events_persister.go`. Version 0.7.22 fixes this issue by using the `SanitizeOrderInput` function.

Meshery is an open source, cloud native manager that enables the design and management of Kubernetes-based infrastructure and applications. A SQL injection vulnerability in Meshery prior to version 0.7.17 allows a remote attacker to obtain sensitive information via the `order` parameter of `GetMeshSyncResources`. Version 0.7.17 contains a patch for this issue.
