Capsule is a multi-tenancy and policy-based framework for Kubernetes. Prior to version 0.1.3, a ServiceAccount deployed in a Tenant Namespace, when granted with `PATCH` capabilities on its own Namespace, is able to edit it and remove the Owner Reference, breaking the reconciliation of the Capsule Operator and removing all the enforcement like Pod Security annotations, Network Policies, Limit Range and Resource Quota items. An attacker could detach the Namespace from a Tenant that is forbidding starting privileged Pods using the Pod Security labels by removing the OwnerReference, removing the enforcement labels, and being able to start privileged containers that would be able to start a generic Kubernetes privilege escalation. Patches have been released for version 0.1.3. No known workarounds are available.

authentik is an open-source identity provider. Versions prior to 2022.11.2 and 2022.10.2 are vulnerable to unauthorized user creation and potential account takeover. With the default flows, unauthenticated users can create new accounts in authentik. If a flow exists that allows for email-verified password recovery, this can be used to overwrite the email address of admin accounts and take over their accounts. authentik 2022.11.2 and 2022.10.2 fix this issue. As a workaround, a policy can be created and bound to the `default-user-settings-flow flow` with the contents `return request.user.is_authenticated`.

IBM has fixed a high-severity security vulnerability affecting its Cloud Databases (ICD) for PostgreSQL product that could be potentially exploited to tamper with internal repositories and run unauthorized code. The privilege escalation flaw (CVSS score: 8.8), dubbed "Hell's Keychain" by cloud security firm Wiz, has been described as a "first-of-its-kind supply-chain attack vector impacting a

The Hell's Keychain attack vector highlights common cloud misconfigurations and secrets exposure that can pose grave risk to enterprise customers.

Current authentication methods are based on the bearer model, but lack of visibility into the entities leveraging API secrets has made this untenable.

Red Hat has issued patches for a bug in an open source Java virtual machine software that opens the door to drive-by localhost attacks. Patch now, as it's easy for cyberattackers to exploit.
