CVE-2026-23989
HighSummary
REVA to platforma interoperacyjna. W wersjach przed 2.42.3 i 2.40.3 występował błąd w middleware autoryzacji GRPC komponentu 'Reva', który pozwalał złośliwemu użytkownikowi na ominięcie weryfikacji zakresu publicznego linku, co umożliwiało stworzenie archiwum zawierającego wszystkie zasoby dostępne dla twórcy tego linku.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do wrażliwych danych, co może prowadzić do wycieku informacji i naruszenia prywatności użytkowników.
Recommendation
Zaleca się aktualizację do wersji 2.42.3 lub 2.40.3, aby usunąć tę podatność oraz przeprowadzenie audytu dostępu do publicznych linków w celu zminimalizowania ryzyka.

- CVE-2026-75885Critical
A flaw was found in the OpenShift console allowing unauthenticated access to the /api/devfile/ and /api/devfile/samples/ endpoints. A remote attacker can send crafted devfile payloads, leading to Server-Side Request Forgery (SSRF) and, by sending repeated large requests without a specified content length, to unbounded memory growth and Denial of Service (DoS).

A buffer overflow vulnerability was found in the Totolink A3002MU (version Hh-B20211125.1046) within the formSchedule function of the /boafrm/formSchedule file. Manipulation of the webpage argument results in a buffer overflow. The attack is possible remotely, and the exploit has been made public.
- CVE-2026-93839Critical
LightLLM through version 1.2.0 contains an authentication bypass vulnerability in the /pd_register WebSocket endpoint that allows unauthenticated attackers to register arbitrary nodes by supplying crafted JSON without peer address validation. Attackers can disclose full user prompts routed to their socket, trigger denial of service by replacing legitimate nodes, or make the PD Master issue requests to internal network addresses.

IBM Guardium Data Protection 12.2 could allow a remote attacker to execute arbitrary SQL commands due to improper neutralization of special elements used in an SQL command.
- CVE-2026-84078Critical
IBM Guardium Data Protection 12.2 is vulnerable to a missing authentication vulnerability in the LoadBalancerServlet. An unauthenticated user can access privileged load-balancer operations, potentially resulting in unauthorized actions and impact to the integrity and availability of the affected system.
- CVE-2026-84075Critical
IBM Guardium Data Protection 12.2 could allow a remote attacker to bypass security restrictions due to missing authentication for the ChangeTrackerServlet.
- CVE-2026-84073Critical
IBM Guardium Data Protection 12.2 could allow a remote authenticated attacker to execute arbitrary SQL commands due to improper neutralization of special elements used in an SQL command.
- CVE-2026-84064Critical
IBM Guardium Data Protection 12.2 could allow a remote authenticated attacker to execute arbitrary SQL commands due to improper neutralization of special elements used in an SQL command.
Original NVD description (English source)
REVA is an interoperability platform. Prior to 2.42.3 and 2.40.3, a bug in the GRPC authorization middleware of the "Reva" component of OpenCloud allows a malicious user to bypass the scope verification of a public link. By exploiting this via the the "archiver" service this can be leveraged to create an archive (zip or tar-file) containing all resources that this creator of the public link has access to. This vulnerability is fixed in 2.42.3 and 2.40.3.
