The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added a critical security flaw impacting Oracle Identity Manager to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability in question is CVE-2025-61757 (CVSS score: 9.8), a case of missing authentication for a critical function that can result in pre-authenticated

### Impact If a schema includes the following characteristics: 1. Permission defined in terms of a union (`+`) 1. That union references the same relation on both sides, but one side arrows to a different permission Then you might have missing `LookupResources` results when checking the permission. This only affects `LookupResources`; other APIs calculate permissionship correctly. A small concrete example: ``` relation doer_of_things: user | group#member permission do_the_thing = doer_of_things + doer_of_things->admin ``` A CheckPermission on `do_the_thing` will return the correct permissionship, but a LookupResources on `do_the_thing` may miss resources. #### A Comprehensive Example If you have a schema with a structure like this: ``` definition special_user {} definition user { relation special_user_mapping: special_user permission special_user = special_user_mapping } definition group { relation member: user permission membership = member + member->special_user } ...

Grafana has released security updates to address a maximum severity security flaw that could allow privilege escalation or user impersonation under certain configurations. The vulnerability, tracked as CVE-2025-41115, carries a CVSS score of 10.0. It resides in the System for Cross-domain Identity Management (SCIM) component that allows automated user provisioning and management. First

SCIM provisioning was introduced in Grafana Enterprise and Grafana Cloud in April to improve how organizations manage users and teams in Grafana by introducing automated user lifecycle management. In Grafana versions 12.x where SCIM provisioning is enabled and configured, a vulnerability in user identity handling allows a malicious or compromised SCIM client to provision a user with a numeric externalId, which in turn could allow to override internal user IDs and lead to impersonation or privilege escalation. This vulnerability applies only if all of the following conditions are met: - `enableSCIM` feature flag set to true - `user_sync_enabled` config option in the `[auth.scim]` block set to true

Vault’s Terraform Provider incorrectly set the default deny_null_bind parameter for the LDAP auth method to false by default, potentially resulting in an insecure configuration. If the underlying LDAP server allowed anonymous or unauthenticated binds, this could result in authentication bypass. This vulnerability, CVE-2025-13357, is fixed in Vault Terraform Provider v5.5.0.
