### Impact A vulnerability was discovered in Argo CD that exposed secret values in error messages and the diff view when an invalid Kubernetes Secret resource was synced from a repository. The vulnerability assumes the user has write access to the repository and can exploit it, either intentionally or unintentionally, by committing an invalid Secret to repository and triggering a Sync. Once exploited, any user with read access to Argo CD can view the exposed secret data. ### Patches A patch for this vulnerability is available in the following Argo CD versions: - v2.13.4 - v2.12.10 - v2.11.13 ### Workarounds There is no workaround other than upgrading. ### References Fixed with commit https://github.com/argoproj/argo-cd/commit/6f5537bdf15ddbaa0f27a1a678632ff0743e4107 & https://github.com/argoproj/gitops-engine/commit/7e21b91e9d0f64104c8a661f3f390c5e6d73ddca

### Impact If the "full-elastic-stack" example vector configuration was used for a real cluster, the previous values of kubernetes secrets would have been disclosed in the audit messages. ### Patches The example has been updated to fix this in commit db1aa5b867256b0a7bf206544c6981ab068b73dc ### Workarounds Replace ```yaml if .request.requestKind.kind == "Secret" { del(.request.object.data) .request.object.data.redacted = "REDACTED" del(.request.oldObject.data) .request.oldObject.data.redacted = "REDACTED" } ``` In the vector "audit-files-json-parser-and-redaction" step with ```yaml if .request.requestKind.kind == "Secret" { # Redact the secret data del(.request.object.data) .request.object.data.redacted = "REDACTED" del(.request.oldObject.data) .request.oldObject.data.redacted = "REDACTED" # Remove the previously set secret data - N...

### Impact A user with access to a Kubernetes cluster where Envoy Gateway is installed can use a path traversal attack to execute Envoy Admin interface commands on proxies managed by Envoy Gateway. The admin interface can be used to terminate the Envoy process and extract the Envoy configuration (possibly containing confidential data). For example, the following command, if run from within the Kubernetes cluster, can be used to get the configuration dump of the proxy: ``` curl --path-as-is http://<Proxy-Service-ClusterIP>:19001/stats/prometheus/../../config_dump ``` ### Patches 1.2.6 ### Workarounds The `EnvoyProxy` API can be used to apply a bootstrap config patch that restricts access strictly to the prometheus stats endpoint. Find below an example of such a bootstrap patch. ``` apiVersion: gateway.envoyproxy.io/v1alpha1 kind: EnvoyProxy metadata: name: custom-proxy-config namespace: default spec: bootstrap: type: JSONPatch jsonPatches: - op: "add" path: ...

### Impact For users who deploy Hubble UI using either Cilium CLI or via the Cilium Helm chart, an insecure default `Access-Control-Allow-Origin` header value could lead to sensitive data exposure. A user with access to a Hubble UI instance affected by this issue could leak configuration details about the Kubernetes cluster which Hubble UI is monitoring, including node names, IP addresses, and other metadata about workloads and the cluster networking configuration. In order for this vulnerability to be exploited, a victim would have to first visit a malicious page. ### Patches This issue was patched in https://github.com/cilium/cilium/commit/a3489f190ba6e87b5336ee685fb6c80b1270d06d This issue affects: - Cilium between v1.14.0 and v1.14.18 inclusive - Cilium between v1.15.0 and v1.15.12 inclusive - Cilium between v1.16.0 and v1.16.5 inclusive This issue is patched in: - Cilium v1.14.19 - Cilium v1.15.13 - Cilium v1.16.6 ### Workarounds Users who deploy Hubble UI using the Ciliu...

### Impact In a Kubernetes cluster where Cilium is configured to proxy DNS traffic, an attacker can crash Cilium agents by sending a crafted DNS response to workloads from outside the cluster. For traffic that is allowed but without using DNS-based policy, the dataplane will continue to pass traffic as configured at the time of the DoS. For workloads that have DNS-based policy configured, existing connections may continue to operate, and new connections made without relying on DNS resolution may continue to be established, but new connections which rely on DNS resolution may be disrupted. Any configuration changes that affect the impacted agent may not be applied until the agent is able to restart. ### Patches This issue affects: - Cilium v1.14 between v1.14.0 and v1.14.17 inclusive - Cilium v1.15 between v1.15.0 and v1.15.11 inclusive - Cilium v1.16 between v1.16.0 and v1.16.4 inclusive This issue is fixed in: - Cilium v1.14.18 - Cilium v1.15.12 - Cilium v1.16.5 ### Workaroun...

A flaw was found in the Hive ClusterDeployments resource in OpenShift Dedicated. In certain conditions, this issue may allow a developer account on a Hive-enabled cluster to obtain cluster-admin privileges by executing arbitrary commands on the hive/hive-controllers pod.

Cybersecurity researchers have uncovered three security weaknesses in Microsoft's Azure Data Factory Apache Airflow integration that, if successfully exploited, could have allowed an attacker to gain the ability to conduct various covert actions, including data exfiltration and malware deployment. "Exploiting these flaws could allow attackers to gain persistent access as shadow administrators

Three vulnerabilities in the service's Apache Airflow integration could have allowed attackers to take shadow administrative control over an enterprise cloud infrastructure, gain access to and exfiltrate data, and deploy malware.
