The Płatnik application from Zakład Ubezpieczeń Społecznych had a vulnerability where client-side authentication was used, allowing attackers with access to any application instance connected to the backend to bypass login verification and authenticate as any user. This issue was fixed in version 10.02.002.
Use of Client-Side authentication vulnerability in Hayat Health Facilities Inc. (Hayat Hospital) Hayat Mobile allows Authentication Bypass.
This issue affects Hayat Mobile: from 3.3.0 before 3.4.0.
CVE-2026-3096 is an improper input validation vulnerability in WSO2 API Control Plane web portals. It arises because external links can be opened in a new browser tab while the originating window retains access to the new page. This allows interaction between the two browser contexts, potentially enabling an attacker to manipulate the original trusted window after a user clicks a malicious external link. Such manipulation can lead to phishing redirections or unauthorized actions within the trusted site context. The vulnerability has a medium severity with a CVSS score of 4.7.
CVE-2026-76945 is a vulnerability in the Ebyte NE2-D11 firmware where authentication tokens are managed by the client without sufficient server-side validation. This flaw allows an attacker to replay or manipulate authentication tokens to gain unauthorized administrative access. The vulnerability has a high severity score of 7.5 and does not require user interaction or privileges to exploit. No affected versions or patch information are provided.
CVE-2026-71187 is a critical vulnerability in the Ebyte NA111-M Firmware version 9013-2-17. The firmware uses client-side authentication logic that can be replicated by unauthenticated attackers. This allows attackers to generate valid authentication requests and bypass authentication controls, gaining administrative access to the device.
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.
Multiple BinSoft products perform client-side authentication. 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.
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.
CVE-2026-1363 is a critical vulnerability in JNC's IAQS product caused by client-side enforcement of server-side security controls (CWE-603). This flaw allows unauthenticated remote attackers to bypass authentication and gain administrator privileges by manipulating the web front-end. The vulnerability requires no user interaction or privileges and can be exploited remotely over the network. With a CVSS 4.0 score of 9.3, it poses a severe risk to confidentiality, integrity, and availability of affected systems. No patches or known exploits are currently reported. European organizations using IAQS, especially in critical infrastructure or industrial automation sectors, face significant risks of unauthorized control and data compromise. Mitigation requires immediate network-level protections, strict access controls, and vendor engagement for patches. Countries with high adoption of JNC IAQS and strategic industrial targets, such as Germany, France, and the Netherlands, are most likely affected.
NMIS/BioDose V22.02 and previous versions rely on a common SQL Server user account to access data in the database. User access in the client application is restricted by a password authentication check in the client software but the underlying database connection always has access. The latest version of NMIS/BioDose introduces an option to use Windows user authentication with the database, which would restrict this database connection.
New Site Server developed by CyberTutor has a Use of Client-Side Authentication vulnerability, allowing unauthenticated remote attackers to modify the frontend code to gain administrator privileges on the website.
The Restaurant Brands International (RBI) assistant platform through 2025-09-06 relies on client-side authentication for submission of equipment orders.
