CVE-2026-0778 1 Enel X 1 Juicebox 40 2026-01-23 N/A
Enel X JuiceBox 40 Telnet Service Missing Authentication Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Enel X JuiceBox 40 charging stations. Authentication is not required to exploit this vulnerability. The specific flaw exists within the telnet service, which listens on TCP port 2000 by default. The issue results from the lack of authentication prior to allowing remote connections. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-23285.
CVE-2026-24423 2026-01-23 N/A
SmarterTools SmarterMail versions prior to build 9511 contain an unauthenticated remote code execution vulnerability in the ConnectToHub API method. The attacker could point the SmarterMail to the malicious HTTP server, which serves the malicious OS command. This command will be executed by the vulnerable application.
CVE-2024-50375 1 Advantech 6 Eki-6333ac-1gpo, Eki-6333ac-1gpo Firmware, Eki-6333ac-2g and 3 more 2026-01-23 9.8 Critical
A CWE-306 "Missing Authentication for Critical Function" was discovered affecting the following devices manufactured by Advantech: EKI-6333AC-2G (<= 1.6.3), EKI-6333AC-2GD (<= v1.6.3) and EKI-6333AC-1GPO (<= v1.2.1). The vulnerability can be exploited by remote unauthenticated users capable of interacting with the default "edgserver" service enabled on the access point.
CVE-2026-1332 1 Hamastar 1 Meetinghub 2026-01-23 5.3 Medium
MeetingHub developed by HAMASTAR Technology has a Missing Authentication vulnerability, allowing unauthenticated remote attackers to access specific API functions and obtain meeting-related information.
CVE-2024-10924 1 Really-simple-plugins 1 Really Simple Security 2026-01-23 9.8 Critical
The Really Simple Security (Free, Pro, and Pro Multisite) plugins for WordPress are vulnerable to authentication bypass in versions 9.0.0 to 9.1.1.1. This is due to improper user check error handling in the two-factor REST API actions with the 'check_login_and_get_user' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, when the "Two-Factor Authentication" setting is enabled (disabled by default).
CVE-2026-1364 2026-01-23 9.8 Critical
IAQS and I6 developed by JNC has a Missing Authentication vulnerability, allowing unauthenticated remote attackers to directly operate system administrative functionalities.
CVE-2026-24124 1 Dragonflyoss 1 Dragonfly2 2026-01-23 N/A
Dragonfly is an open source P2P-based file distribution and image acceleration system. In versions 2.4.1-rc.0 and below, the Job API endpoints (/api/v1/jobs) lack JWT authentication middleware and RBAC authorization checks in the routing configuration. This allows any unauthenticated user with access to the Manager API to view, update and delete jobs. The issue is fixed in version 2.4.1-rc.1.
CVE-2025-54816 1 Evmapa 1 Evmapa 2026-01-23 9.4 Critical
This vulnerability occurs when a WebSocket endpoint does not enforce proper authentication mechanisms, allowing unauthorized users to establish connections. As a result, attackers can exploit this weakness to gain unauthorized access to sensitive data or perform unauthorized actions. Given that no authentication is required, this can lead to privilege escalation and potentially compromise the security of the entire system.
CVE-2021-47802 1 Tenda 2 D151, D301 2026-01-22 7.5 High
Tenda D151 and D301 routers contain an unauthenticated configuration download vulnerability that allows remote attackers to retrieve router configuration files. Attackers can send a request to /goform/getimage endpoint to download configuration data including admin credentials without authentication.
CVE-2025-63391 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-01-22 7.5 High
An authentication bypass vulnerability exists in Open-WebUI <=0.6.32 in the /api/config endpoint. The endpoint lacks proper authentication and authorization controls, exposing sensitive system configuration data to unauthenticated remote attackers.
CVE-2025-63390 1 Mintplexlabs 1 Anythingllm 2026-01-22 5.3 Medium
An authentication bypass vulnerability exists in AnythingLLM v1.8.5 in via the /api/workspaces endpoint. The endpoint fails to implement proper authentication checks, allowing unauthenticated remote attackers to enumerate and retrieve detailed information about all configured workspaces. Exposed data includes: workspace identifiers (id, name, slug), AI model configurations (chatProvider, chatModel, agentProvider), system prompts (openAiPrompt), operational parameters (temperature, history length, similarity thresholds), vector search settings, chat modes, and timestamps.
CVE-2025-63389 1 Ollama 1 Ollama 2026-01-22 9.8 Critical
A critical authentication bypass vulnerability exists in Ollama platform's API endpoints in versions prior to and including v0.12.3. The platform exposes multiple API endpoints without requiring authentication, enabling remote attackers to perform unauthorized model management operations.
CVE-2025-63896 2 Jxl, Jxlindia 3 Jxl Double Din Player, Jxl 9 Inch Car Android Double Din Player, Jxl 9 Inch Car Android Double Din Player Firmware 2026-01-22 7.6 High
An issue in the Bluetooth Human Interface Device (HID) of JXL 9 Inch Car Android Double Din Player Android v12.0 allows attackers to inject arbitrary keystrokes via a spoofed Bluetooth HID device.
CVE-2025-31963 1 Hcltech 1 Bigfix Insights For Vulnerability Remediation 2026-01-22 2.9 Low
Improper authentication and missing CSRF protection in the local setup interface component in HCL BigFix IVR version 4.2 allows a local attacker to perform unauthorized configuration changes via unauthenticated administrative configuration requests.
CVE-2025-69285 1 Dataease 1 Sqlbot 2026-01-22 N/A
SQLBot is an intelligent data query system based on a large language model and RAG. Versions prior to 1.5.0 contain a missing authentication vulnerability in the /api/v1/datasource/uploadExcel endpoint, allowing a remote unauthenticated attacker to upload arbitrary Excel/CSV files and inject data directly into the PostgreSQL database. The endpoint is explicitly added to the authentication whitelist, causing the TokenMiddleware to bypass all token validation. Uploaded files are parsed by pandas and inserted into the database via to_sql() with if_exists='replace' mode. The vulnerability has been fixed in v1.5.0. No known workarounds are available.
CVE-2026-23944 1 Getarcaneapp 1 Arcane 2026-01-21 N/A
Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to version 1.13.2, unauthenticated requests could be proxied to remote environment agents, allowing access to remote environment resources without authentication. The environment proxy middleware handled `/api/environments/{id}/...` requests for remote environments before authentication was enforced. When the environment ID was not local, the middleware proxied the request and attached the manager-held agent token, even if the caller was unauthenticated. This enabled unauthenticated access to remote environment operations (e.g., listing containers, streaming logs, or other agent endpoints). An unauthenticated attacker could access and manipulate remote environment resources via the proxy, potentially leading to data exposure, unauthorized changes, or service disruption. Version 1.13.2 patches the vulnerability.
CVE-2026-22788 1 Wem-project 1 Wem 2026-01-21 8.2 High
WebErpMesv2 is a Resource Management and Manufacturing execution system Web for industry. Prior to 1.19, the WebErpMesV2 application exposes multiple sensitive API endpoints without authentication middleware. An unauthenticated remote attacker can read business-critical data including companies, quotes, orders, tasks, and whiteboards. Limited write access allows creation of company records and full manipulation of collaboration whiteboards. This vulnerability is fixed in 1.19.
CVE-2025-65824 1 Meatmeet 3 Meatmeet, Meatmeet Pro Wifi \& Bluetooth Meat Thermometer, Meatmeet Pro Wifi \& Bluetooth Meat Thermometer Firmware 2026-01-21 8.8 High
An unauthenticated attacker within proximity of the Meatmeet device can perform an unauthorized Over The Air (OTA) firmware upgrade using Bluetooth Low Energy (BLE), resulting in the firmware on the device being overwritten with the attacker's code. As the device does not perform checks on upgrades, this results in Remote Code Execution (RCE) and the victim losing complete access to the Meatmeet.
