CVE-2026-9152A missing authentication vulnerability exists in the Altium 365 SearchService. A legacy SOAP endpoint exposes search index operations without requiring authentication, session tokens, or any form of identity verification. An unauthenticated network attacker who can reference a target workspace's identifier can interact with that workspace's search index, crossing tenant boundaries.
Successful exploitation allows reading a workspace's indexed contents (such as component data, project and folder names, and user metadata) and injecting, modifying, or deleting search index entries. These operations affect the search index only, not the underlying vault data, but they can disclose sensitive workspace information and compromise the integrity and availability of search results. Altium 365 cloud deployments are affected; on-premise Altium Enterprise Server is not affected.
CVE-2026-44329free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's SMF mounts the UPI management route group without OAuth2/bearer-token authorization middleware. A network attacker who can reach SMF on the SBI can hit UPI endpoints with no Authorization header at all, and the requests reach the SMF business handlers. In the running Docker lab this was directly demonstrated for read (GET /upi/v1/upNodesLinks), write (POST /upi/v1/upNodesLinks with attacker-controlled UP-node and link payload), and delete (DELETE /upi/v1/upNodesLinks/{nodeID}) operations. This vulnerability is fixed in 4.2.2.
CVE-2026-44327free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's NEF mounts the nnef-oam route group without inbound OAuth2/bearer-token authorization. A network attacker who can reach NEF on the SBI can hit the OAM route with no Authorization header at all and the handler returns 200 OK. The current OAM handler is a stub that returns null, but the structural defect is route-group-scoped: the entire OAM route group has no inbound auth middleware, so every future OAM operation added to this group inherits the missing auth boundary by default. This vulnerability is fixed in 4.2.2.
CVE-2026-3611The Honeywell IQ4x building management controller, exposes its full web-based HMI without authentication in its factory-default configuration. With no user module configured, security is disabled by design and the system operates under a System Guest (level 100) context, granting read/write privileges to any party able to reach the HTTP interface. Authentication controls are only enforced after a web user is created via U.htm, which dynamically enables the user module. Because this function is accessible prior to authentication, a remote user can create a new account with administrative read/write permissions enabling the user module and imposing authentication under attacker-controlled credentials. This action can effectively lock legitimate operators out of local and web-based configuration and administration.
CVE-2026-34162FastGPT is an AI Agent building platform. Prior to version 4.14.9.5, the FastGPT HTTP tools testing endpoint (/api/core/app/httpTools/runTool) is exposed without any authentication. This endpoint acts as a full HTTP proxy — it accepts a user-supplied baseUrl, toolPath, HTTP method, custom headers, and body, then makes a server-side HTTP request and returns the complete response to the caller. This issue has been patched in version 4.14.9.5.
CVE-2026-26333Calero VeraSMART versions prior to 2022 R1 expose an unauthenticated .NET Remoting HTTP service on TCP port 8001. The service publishes default ObjectURIs (including EndeavorServer.rem and RemoteFileReceiver.rem) and permits the use of SOAP and binary formatters with TypeFilterLevel set to Full. An unauthenticated remote attacker can invoke the exposed remoting endpoints to perform arbitrary file read and write operations via the WebClient class. This allows retrieval of sensitive files such as WebRoot\\web.config, which may disclose IIS machineKey validation and decryption keys. An attacker can use these keys to generate a malicious ASP.NET ViewState payload and achieve remote code execution within the IIS application context. Additionally, supplying a UNC path can trigger outbound SMB authentication from the service account, potentially exposing NTLMv2 hashes for relay or offline cracking.
CVE-2026-2577The WhatsApp bridge component in Nanobot binds the WebSocket server to all network interfaces (0.0.0.0) on port 3001 by default and does not require authentication for incoming connections. An unauthenticated remote attacker with network access to the bridge can connect to the WebSocket server to hijack the WhatsApp session. This allows the attacker to send messages on behalf of the user, intercept all incoming messages and media in real-time, and capture authentication QR codes.
CVE-2026-20223A vulnerability in the access validation of internal REST APIs of Cisco Secure Workload could allow an unauthenticated, remote attacker to access site resources with the privileges of the Site Admin role.
This vulnerability is due to insufficient validation and authentication when accessing REST API endpoints. An attacker could exploit this vulnerability if they are able to send a crafted API request to an affected endpoint. A successful exploit could allow the attacker to read sensitive information and make configuration changes across tenant boundaries with the privileges of the Site Admin user.
CVE-2026-1633The Synectix LAN 232 TRIO 3-Port serial to ethernet adapter exposes its web management interface without requiring authentication, allowing unauthenticated users to modify critical device settings or factory reset the device.
CVE-2025-69425The Ruckus vRIoT IoT Controller firmware versions prior to 3.0.0.0 (GA) expose a command execution service on TCP port 2004 running with root privileges. Authentication to this service relies on a hardcoded Time-based One-Time Password (TOTP) secret and an embedded static token. An attacker who extracts these credentials from the appliance or a compromised device can generate valid authentication tokens and execute arbitrary OS commands with root privileges, resulting in complete system compromise.
CVE-2025-61956Radiometrics VizAir is vulnerable to a lack of authentication mechanisms for critical functions, such as admin access and API requests. Attackers can modify configurations without authentication, potentially manipulating active runway settings and misleading air traffic control (ATC) and pilots. Additionally, manipulated meteorological data could mislead forecasters and ATC, causing inaccurate flight planning.
CVE-2025-61945Radiometrics VizAir is vulnerable to any remote attacker via access to the admin panel of the VizAir system without authentication. Once inside, the attacker can modify critical weather parameters such as wind shear alerts, inversion depth, and CAPE values, which are essential for accurate weather forecasting and flight safety. This unauthorized access could result in the disabling of vital alerts, causing hazardous conditions for aircraft, and manipulating runway assignments, which could result in mid-air conflicts or runway incursions.
CVE-2025-52665A malicious actor with access to the management network could exploit a misconfiguration in UniFi’s door access application, UniFi Access, that exposed a management API without proper authentication. This vulnerability was introduced in Version 3.3.22 and was fixed in Version 4.0.21 and later.
Affected Products:
UniFi Access Application (Version 3.3.22 through 3.4.31).
Mitigation:
Update your UniFi Access Application to Version 4.0.21 or later.
CVE-2025-41656An unauthenticated remote attacker can run arbitrary commands on the affected devices with high privileges because the authentication for the Node_RED server is not configured by default.
CVE-2025-36535The embedded web server lacks authentication and access controls, allowing unrestricted remote access. This could lead to configuration changes, operational disruption, or arbitrary code execution depending on the environment and exposed functionality.
