CVE-2026-12212MEDIUM 4.3

A vulnerability has been found in hcengineering Huly Platform up to 0.7.0. Affected is the function getMailboxSecret of the file server/account/src/operations.ts of the component RPC Interface. The manipulation leads to improper access controls. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2026-41856HIGH 7.5

The Spring GraphQL annotation detection mechanism for @Controller data fetchers may not correctly resolve annotations on methods within type hierarchies. This can be an issue if such annotations are used for authorization decisions. When all conditions are met, security annotations can be ignored at runtime. Affected versions: Spring for GraphQL 2.0.0 through 2.0.3; 1.4.0 through 1.4.5; 1.3.0 through 1.3.8; 1.0.0 through 1.0.6.

CVE-2026-45776MEDIUM 4.3

OpenXDMoD is an open framework for collecting and analyzing HPC metrics. Prior to version 11.0.3, a flaw in Open XDMoD's access control logic allows an attacker to submit a crafted HTTPS POST request that sets a session variable used for authorization decisions. If an installation of Open XDMoD includes the optional Job Performance (SUPReMM) module, an attacker could bypass intended data access restrictions and view other users' compute job efficiency metrics. All deployments of Open XDMoD prior to version 11.0.3 that contain the optional Job Performance (SUPReMM) module are impacted. This issue was reported privately on 2026-04-06, and at this time there is no evidence that this vulnerability has been exploited in the wild. The vulnerability was patched in Open XDMoD 11.0.3 on 2026-05-12. As a workaround, apply the patch manually.

CVE-2026-8033MEDIUM 5.3

A vulnerability has been found in PicoTronica e-Clinic Healthcare System ECHS 5.7. This affects an unknown function of the file /cdemos/echs/api/v2/ of the component Response Header Handler. Such manipulation leads to information disclosure. The attack may be performed from remote. The exploit has been disclosed to the public and may be used. Upgrading to version 5.7.1 mitigates this issue. It is suggested to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

CVE-2026-7021LOW 3.5

A weakness has been identified in SmythOS sre up to 0.0.15. This impacts an unknown function of the file packages/sdk/src/LLM/utils.ts of the component Connector Service. This manipulation of the argument baseURL causes information disclosure. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2026-22313CRITICAL 9.1

The device has a webserver that exposes a REST API authenticated with a token on the management network. By exploiting an OS command injection vulnerability an authenticated attacker can send arbitrary commands to the device that are executed with administrative permissions by the underlying operating system.

CVE-2026-11526CRITICAL 9.8

GD versions before 2.86 for Perl allow OS command injection and file overwrite via a 2-arg open() of filename arguments in _make_filehandle. GD::Image::_make_filehandle opens a filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe ("| cmd", "cmd |") or begins with a redirect ("> path", ">> path") is run as a command or redirect rather than opened as a file. _make_filehandle is the single open path behind every filename-accepting constructor (new, newFromPng, newFromJpeg, and the rest); the in-memory *Data variants do not open a path and are unaffected. Any caller that forwards untrusted input to one of these constructors as a pathname can run an arbitrary command or truncate a file under the process UID.

CVE-2026-12183CRITICAL 9.8

Nefteprodukttekhnika BUK TS-G Gas Station Automation System 2.9.1 through 2.10.2 on Linux contains an Improper Authentication vulnerability (CWE-287) in the system configuration module. The /php/ajax-login.php endpoint returns userid=1 (administrator) in response to any HTTP POST request that supplies arbitrary credentials (e.g., action=dologin&login=<any_value>&pwd=<any_value>), and subsequent privileged endpoints under /php/ajax-main.php and /modules/* do not validate a server-side session. A remote unauthenticated attacker can invoke any administrative action exposed by the configuration module, including reading and modifying user rules, fuel tank gauges, fuel dispensers, relays, cash registers, bank terminals, fuel cards, price and customer displays, cash collection, and pricing rules.

CVE-2026-53838CRITICAL 9.8

OpenClaw before 2026.5.27 contains a state mutation vulnerability in node pairing reconnection that allows paired nodes to confuse approval scope decisions. Attackers can exploit reconnection logic to restore or present broader node authority than intended, potentially bypassing approval restrictions.

CVE-2026-50628CRITICAL 9.8

A logic error in OAuthRequestFilter rejects legitimate requests originating from the bound IP address, while blindly allowing requests from any other IP address. Enabling this security feature inadvertently creates an inverse security check. Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.
