CVE-2026-42098 Alta · 8.7 CWE-603 19/05/2026
Authorization Bypass in Sparx Enterprise Architect
Sparx Enterprise Architect software has a security feature that limits user's actions to those specified in the role. An authenticated attacker can modify the Enterprise Architect client behavior (e.g. using a debugger) and log in as any other user or administrator - then it is possible to do every possible change to the repository. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 17.1 and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
CVE-2026-8830 Média · 4.3 CWE-603 19/05/2026
Keycloak: org.keycloak/keycloak-services: keycloak: policy bypass during webauthn credential registration via client-side javascript manipulation
A flaw was found in Keycloak. An authenticated user can bypass configured WebAuthn policies during credential registration by manipulating client-side JavaScript. This occurs because the server-side processAction() fails to validate that the newly created credential's parameters, such as public key algorithms, match the realm's configured WebAuthn policies. This could lead to the creation of credentials that do not adhere to administrative security requirements, potentially weakening the overall security posture of the system by allowing non-compliant authentication methods.
CVE-2026-40551 Alta · 8.4 CWE-603 28/04/2026
Use of Client-Side Authentication in multiple BinSoft products

An attacker with access to any application instance connected to the backend server can bypass the login verification process by manipulating the application binary and authenticate as an arbitrary user. The described issue affects all published versions. The vendor stated that this issue is a direct result of the architecture model in which the software is distributed, and that it will be mitigated with a corrected installation manual.
CVE-2025-30042 Alta · 7.8 CWE-603 02/03/2026
Session generation possible with certificate number only
The CGM CLININET system provides smart card authentication; however, authentication is conducted locally on the client device, and, in reality, only the certificate number is used for access verification. As a result, possession of the certificate number alone is sufficient for authentication, regardless of the actual presence of the smart card or ownership of the private key.
