CVE-2026-255559.8 CRI71.6%
——21OpenBullet2 through version 0.3.2 contains an authentication bypass vulnerability in the API key authentication middleware that allows unauthenticated attackers to gain admin access by supplying an empty X-Api-Key header value. Attackers can exploit the middleware's comparison of the supplied header against an empty AdminApiKey default string to access the admin console and all API endpoints without valid credentials.3dCVE-2026-409769.1 CRI38.8%
——12In certain circumstances, Spring Boot's default web security is ineffective allowing unauthorized access to all endpoints. For an application to be vulnerable, it must: be a servlet-based web application; have no Spring Security configuration of its own and rely on the default web security filter chain; depend on spring-boot-actuator-autoconfigure; not depend on spring-boot-health. If any of the above does not apply, the application is not vulnerable.
Affected: Spring Boot 4.0.0–4.0.5; upgrade to 4.0.6 or later per vendor advisory.3dCVE-2026-30478.8 HIG37.6%
——11A flaw was found in org.keycloak.broker.saml. When a disabled Security Assertion Markup Language (SAML) client is configured as an Identity Provider (IdP)-initiated broker landing target, it can still complete the login process and establish a Single Sign-On (SSO) session. This allows a remote attacker to gain unauthorized access to other enabled clients without re-authentication, effectively bypassing security restrictions.3dCVE-2026-62668.3 HIG32.0%
——10A flaw was found in the AAP gateway. The user auto-link strategy, introduced in AAP 2.6, automatically links an external Identity Provider (IDP) identity to an existing AAP user account based on email matching without verifying email ownership. This allows a remote attacker to potentially hijack a victim's account or gain unauthorized access to other accounts, including administrative accounts, by manipulating the IDP-provided email.3dCVE-2026-410528.8 HIG23.9%
——7Improper privilege handling could be used by users with Project Owner role to escalate privileges, in Rancher versions 2.14 before 2.14.2, 2.13 before 2.13.6, and 2.12 before 2.12.10.15dCVE-2026-105399.0 CRI14.5%
——4A Control-M/Server communication command does not sufficiently filter or sanitize user-supplied input. Under certain conditions, this issue may allow an unauthenticated attacker to execute unauthorized commands on the affected server, potentially leading to compromise of the server.
This vulnerability affects Control-M/Server versions 9.0.20.x to 9.0.21.200 (included) and potentially earlier unsupported versions.16d
