CVE-2025-14963
HighSummary
W podatności CVE-2025-14963 zidentyfikowano problem w pliku sterownika HX Agent (fekern.sys), który umożliwia lokalnemu użytkownikowi uzyskanie podwyższonych uprawnień systemowych. Wykorzystanie podatnego sterownika w ramach Bring Your Own Vulnerable Driver (BYOVD) pozwala na dostęp do krytycznego procesu pamięci Windows lsass.exe.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do krytycznych zasobów systemowych, co może prowadzić do poważnych naruszeń bezpieczeństwa. Potencjalne wykorzystanie tej podatności może skutkować utratą danych lub przejęciem kontroli nad systemem.
Recommendation
Zaleca się monitorowanie i aktualizację systemów oraz sterowników HX Agent, aby zminimalizować ryzyko wykorzystania tej podatności. Należy również wdrożyć dodatkowe środki zabezpieczające, aby ograniczyć dostęp lokalnych użytkowników do krytycznych procesów systemowych.

The wpShopGermany IT-RECHT KANZLEI WordPress plugin before 2.4 does not generate its API authentication token securely, deriving it from data the requester controls and creating it as a side effect of the check that is supposed to validate it. This allows unauthenticated attackers to predict the token and use the access it grants to write arbitrary files, leading to remote code execution.

The Login with QR WordPress plugin through 1.0.0 does not verify that the code used to log a user in is one it issued, matching any stored user metadata value instead. This allows unauthenticated attackers to log in as any user, including administrators.
- CVE-2026-86709Critical
The Pressengine WordPress plugin through 1.0 does not stop its login handler from issuing a session when authentication fails. This allows unauthenticated attackers to log in as any user, including administrators.

The Private Feed Key WordPress plugin through 0.1 does not verify that the key used to authenticate a feed request is one it issued, matching any stored user metadata value instead. This allows unauthenticated attackers to log in as any user, including administrators.
- CVE-2026-87796Critical
The Multi Uploader for Gravity Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to and including 1.1.9 via the move_file function. This is due to insufficient file type validation during chunked upload handling. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

djust prior to version 1.0.7 has a vulnerability in the WebSocket transport that bypasses standard Django authorization mechanisms (such as LoginRequiredMixin, PermissionRequiredMixin, etc.) and the staff gate in the admin extension. Mount authorization is done via check_view_auth, not the View.dispatch() chain, allowing anonymous or under-privileged clients to open a WebSocket and dispatch view handlers, including admin ones.

UVdesk Community Skeleton through 1.1.8 fails to authenticate or validate installation state on wizard endpoints in ConfigureHelpdesk controller actions. Unauthenticated attackers can repoint the database and create super administrator accounts by submitting crafted requests to wizard endpoints, gaining full control of the instance.
- CVE-2026-92787Critical
Feast through 0.66.0 fails to verify JWT token signatures before establishing user identity, allowing attackers to bypass all role-based access control by presenting an unverified token with a hardcoded claim value. Attackers can obtain trusted internal identity and gain unchecked read and write access to all entities, feature views, data sources, and permission policies on the server.
- CVE-2026-76460CriticalActively exploited
A vulnerability in the API of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to bypass authentication. This is due to insufficient authentication control on an API endpoint. An attacker could send a crafted request to gain unauthorized access to the device by bypassing the web-based management interface.
Original NVD description (English source)
A vulnerability identified in the HX Agent driver file fekern.sys allowed a threat actor with local user access the ability to gain elevated system privileges. Utilization of a Bring Your Own Vulnerable Driver (BYOVD) was leveraged to gain access to the critical Windows process memory lsass.exe (Local Security Authority Subsystem Service). The fekern.sys is a driver file associated with the HX Agent (used in all existing HX Agent versions). The vulnerable driver installed in a product or a system running a fully functional HX Agent is, itself, not exploitable as the product’s tamper protection restricts the ability to communicate with the driver to only the Agent’s processes.
