CVE-2026-40344 1 Minio 1 Minio 2026-04-27 8.2 High
MinIO is a high-performance object storage system. Starting in RELEASE.2023-05-18T00-05-36Z and prior to RELEASE.2026-04-11T03-20-12Z, an authentication bypass vulnerability in MinIO's Snowball auto-extract handler (`PutObjectExtractHandler`) allows any user who knows a valid access key to write arbitrary objects to any bucket without knowing the secret key or providing a valid cryptographic signature. Any MinIO deployment is impacted. The attack requires only a valid access key (the well-known default `minioadmin`, or any key with WRITE permission on a bucket) and a target bucket name. When `authTypeStreamingUnsignedTrailer` support was added, the new auth type was handled in `PutObjectHandler` and `PutObjectPartHandler` but was never added to `PutObjectExtractHandler`. The snowball auto-extract handler's `switch rAuthType` block has no case for `authTypeStreamingUnsignedTrailer`, so execution falls through with zero signature verification. The `isPutActionAllowed` call before the switch extracts the access key and checks IAM permissions, but does not verify the cryptographic signature. An attacker sends a PUT request with `X-Amz-Content-Sha256: STREAMING-UNSIGNED-PAYLOAD-TRAILER`, `X-Amz-Meta-Snowball-Auto-Extract: true`, and an `Authorization` header containing a valid access key with a completely fabricated signature. The request is accepted and the tar payload is extracted into the bucket. Users of the open-source minio/minio project should upgrade to MinIO AIStor RELEASE.2026-04-11T03-20-12Z or later. If upgrading is not immediately possible, block unsigned-trailer requests at the load balancer. Reject any request containing X-Amz-Content-Sha256: STREAMING-UNSIGNED-PAYLOAD-TRAILER at the reverse proxy or WAF layer. Clients can use STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER (the signed variant) instead. Alternatively, restrict WRITE permissions. Limit s3:PutObject grants to trusted principals. While this reduces the attack surface, it does not eliminate the vulnerability since any user with WRITE permission can exploit it with only their access key.
CVE-2026-41176 1 Rclone 1 Rclone 2026-04-27 9.8 Critical
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. The RC endpoint `options/set` is exposed without `AuthRequired: true`, but it can mutate global runtime configuration, including the RC option block itself. Starting in version 1.45.0 and prior to version 1.73.5, an unauthenticated attacker can set `rc.NoAuth=true`, which disables the authorization gate for many RC methods registered with `AuthRequired: true` on reachable RC servers that are started without global HTTP authentication. This can lead to unauthorized access to sensitive administrative functionality, including configuration and operational RC methods. Version 1.73.5 patches the issue.
CVE-2026-41179 1 Rclone 1 Rclone 2026-04-27 9.8 Critical
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Starting in version 1.48.0 and prior to version 1.73.5, the RC endpoint `operations/fsinfo` is exposed without `AuthRequired: true` and accepts attacker-controlled `fs` input. Because `rc.GetFs(...)` supports inline backend definitions, an unauthenticated attacker can instantiate an attacker-controlled backend on demand. For the WebDAV backend, `bearer_token_command` is executed during backend initialization, making single-request unauthenticated local command execution possible on reachable RC deployments without global HTTP authentication. Version 1.73.5 patches the issue.
CVE-2026-32297 1 Angeet 2 Es3 Kvm, Es3 Kvm Firmware 2026-04-27 7.5 High
The Angeet ES3 KVM allows a remote, unauthenticated attacker to write arbitrary files, including configuration files or system binaries. Modified configuration files or system binaries could allow an attacker to take complete control of a vulnerable system.
CVE-2026-40884 2 Goshs, Patrickhener 2 Goshs, Goshs 2026-04-27 9.8 Critical
goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.6, goshs contains an SFTP authentication bypass when the documented empty-username basic-auth syntax is used. If the server is started with -b ':pass' together with -sftp, goshs accepts that configuration but does not install any SFTP password handler. As a result, an unauthenticated network attacker can connect to the SFTP service and access files without a password. This vulnerability is fixed in 2.0.0-beta.6.
CVE-2026-3558 2 Philips, Phillips 3 Hue Bridge V2, Hue Bridge V2 Firmware, Hue Bridge 2026-04-27 N/A
Philips Hue Bridge HomeKit Accessory Protocol Transient Pairing Mode Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Philips Hue Bridge. Authentication is not required to exploit this vulnerability. The specific flaw exists within the configuration of the HomeKit Accessory Protocol service, which listens on TCP port 8080 by default. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-28374.
CVE-2026-30836 1 Smallstep 2 Certificates, Step-ca 2026-04-27 10 Critical
Step CA is an online certificate authority for secure, automated certificate management for DevOps. Versions 0.30.0-rc6 and below do not safeguard against unauthenticated certificate issuance through the SCEP UpdateReq. This issue has been fixed in version 0.30.0.
CVE-2026-32291 1 Gl-inet 3 Comet Gl-rm1, Comet Gl-rm1 Firmware, Comet Kvm 2026-04-27 6.8 Medium
The GL-iNet Comet (GL-RM1) KVM before 1.8.2 does not require authentication on the UART serial console. This attack requires physically opening the device and connecting to the UART pins.
CVE-2025-35051 1 Newforma 2 Project Center, Project Center Server 2026-04-26 9.8 Critical
Newforma Project Center Server (NPCS) accepts serialized .NET data via the '/ProjectCenter.rem' endpoint on 9003/tcp, allowing a remote, unauthenticated attacker to execute arbitrary code with 'NT AUTHORITY\NetworkService' privileges. According to the recommended architecture, the vulnerable NPCS endpoint is only accessible on an internal network. To mitigate this vulnerability, restrict network access to NPCS.
CVE-2026-26159 1 Microsoft 30 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 27 more 2026-04-24 7.8 High
Missing authentication for critical function in Windows Remote Desktop Licensing Service allows an authorized attacker to elevate privileges locally.
CVE-2026-26160 1 Microsoft 30 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 27 more 2026-04-24 7.8 High
Missing authentication for critical function in Windows Remote Desktop Licensing Service allows an authorized attacker to elevate privileges locally.
CVE-2026-41273 1 Flowiseai 1 Flowise 2026-04-24 8.2 High
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, Flowise contains an authentication bypass vulnerability that allows an unauthenticated attacker to obtain OAuth 2.0 access tokens associated with a public chatflow. By accessing a public chatflow configuration endpoint, an attacker can retrieve internal workflow data, including OAuth credential identifiers, which can then be used to refresh and obtain valid OAuth 2.0 access tokens without authentication. This vulnerability is fixed in 3.1.0.
CVE-2026-34839 1 Nicolargo 1 Glances 2026-04-24 6.5 Medium
Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.4, the Glances web server exposes a REST API (`/api/4/*`) that is accessible without authentication and allows cross-origin requests from any origin due to a permissive CORS policy (`Access-Control-Allow-Origin: *`). This allows a malicious website to read sensitive system information from a running Glances instance in the victim’s browser, leading to cross-origin data exfiltration. While a previous advisory exists for XML-RPC CORS issues, this report demonstrates that the REST API (`/api/4/*`) is also affected and exposes significantly more sensitive data. Version 4.5.4 patches the issue.

CVE-2026-39987 2 Coreweave, Marimo-team 2 Marimo, Marimo 2026-04-24 9.8 Critical
marimo is a reactive Python notebook. Prior to 0.23.0, Marimo has a Pre-Auth RCE vulnerability. The terminal WebSocket endpoint /terminal/ws lacks authentication validation, allowing an unauthenticated attacker to obtain a full PTY shell and execute arbitrary system commands. Unlike other WebSocket endpoints (e.g., /ws) that correctly call validate_auth() for authentication, the /terminal/ws endpoint only checks the running mode and platform support before accepting connections, completely skipping authentication verification. This vulnerability is fixed in 0.23.0.
