CVE-2026-26127 3 Apple, Linux, Microsoft 5 Macos, Linux Kernel, .net and 2 more 2026-06-17 N/A 7.5 HIGH
Out-of-bounds read in .NET allows an unauthorized attacker to deny service over a network.
CVE-2026-25766 2 Labstack, Microsoft 2 Echo, Windows 2026-06-17 N/A 5.3 MEDIUM
Echo is a Go web framework. In versions 5.0.0 through 5.0.2 on Windows, Echo’s `middleware.Static` using the default filesystem allows path traversal via backslashes, enabling unauthenticated remote file read outside the static root. In `middleware/static.go`, the requested path is unescaped and normalized with `path.Clean` (URL semantics). `path.Clean` does not treat `\` as a path separator, so `..\` sequences remain in the cleaned path. The resulting path is then passed to `currentFS.Open(...)`. When the filesystem is left at the default (nil), Echo uses `defaultFS` which calls `os.Open` (`echo.go:792`). On Windows, `os.Open` treats `\` as a path separator and resolves `..\`, allowing traversal outside the static root. Version 5.0.3 fixes the issue.
CVE-2026-25228 2 Microsoft, Signalk 2 Windows, Signal K Server 2026-06-17 N/A 5.0 MEDIUM
Signal K Server is a server application that runs on a central hub in a boat. Prior to 2.20.3, a path traversal vulnerability in SignalK Server's applicationData API allows authenticated users on Windows systems to read, write, and list arbitrary files and directories on the filesystem. The validateAppId() function blocks forward slashes (/) but not backslashes (\), which are treated as directory separators by path.join() on Windows. This enables attackers to escape the intended applicationData directory. This vulnerability is fixed in 2.20.3.
CVE-2026-24413 2 Icinga, Microsoft 2 Icinga, Windows 2026-06-17 N/A 5.5 MEDIUM
Icinga 2 is an open source monitoring system. Starting in version 2.3.0 and prior to versions 2.13.14, 2.14.8, and 2.15.2, the Icinga 2 MSI did not set appropriate permissions for the `%ProgramData%\icinga2\var` folder on Windows. This resulted in the its contents - including the private key of the user and synced configuration - being readable by all local users. All installations on Windows are affected. Versions 2.13.14, 2.14.8, and 2.15.2 contains a fix. There are two possibilities to work around the issue without upgrading Icinga 2. Upgrade Icinga for Windows to at least version v1.13.4, v1.12.4, or v1.11.2. These version will automatically fix the ACLs for the Icinga 2 agent as well. Alternatively, manually update the ACL for the given folder `C:\ProgramData\icinga2\var` (and `C:\Program Files\WindowsPowerShell\modules\icinga-powershell-framework\certificate` to fix the issue for the Icinga for Windows as well) including every sub-folder and item to restrict access for general users, only allowing the Icinga service user and administrators access.
CVE-2026-23889 2 Microsoft, Pnpm 2 Windows, Pnpm 2026-06-17 N/A 6.5 MEDIUM
pnpm is a package manager. Prior to version 10.28.1, a path traversal vulnerability in pnpm's tarball extraction allows malicious packages to write files outside the package directory on Windows. The path normalization only checks for `./` but not `.\`. On Windows, backslashes are directory separators, enabling path traversal. This vulnerability is Windows-only. This issue impacts Windows pnpm users and Windows CI/CD pipelines (GitHub Actions Windows runners, Azure DevOps). It can lead to overwriting `.npmrc`, build configs, or other files. Version 10.28.1 contains a patch.
CVE-2026-23571 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 6.8 MEDIUM
A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Nomad-RunPkgStatusRequest instruction. Improper input validation allows authenticated attackers with actioner privilege to run elevated arbitrary commands on connected hosts via malicious commands injected into the instruction’s input field. Users of 1E Client version 24.5 or higher are not affected.
CVE-2026-23570 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 6.5 MEDIUM
A missing validation of a user-controlled value in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an adjacent network attacker to tamper with log timestamps via crafted UDP Sync command. This could result in forged or nonsensical datetime prefixes and compromising log integrity and forensic correlation.
CVE-2026-23569 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 6.5 MEDIUM
An out-of-bounds read vulnerability in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows a remote attacker to leak stack memory and cause a denial of service via a crafted request. The leaked stack memory could be used to bypass ASLR remotely and facilitate exploitation of other vulnerabilities on the affected system.
CVE-2026-23568 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 5.4 MEDIUM
An out-of-bounds read vulnerability in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to cause information disclosure or denial-of-service via a special crafted packet. The leaked memory could be used to bypass ASLR and facilitate further exploitation.
CVE-2026-23567 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 6.5 MEDIUM
An integer underflow in the UDP command handler of the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an adjacent network attacker to trigger a heap-based buffer overflow and cause a denial-of-service (service crash) via specially crafted UDP packets.
CVE-2026-23566 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 6.5 MEDIUM
A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to inject, tamper with, or forge log entries in \Nomad Branch.log via crafted data sent to the UDP network handler. This can impact log integrity and nonrepudiation.
CVE-2026-23565 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 6.5 MEDIUM
A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to cause the NomadBranch.exe process to terminate via crafted requests. This can result in a denial-of-service condition of the Content Distribution Service.
CVE-2026-23564 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 6.5 MEDIUM
A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to cause normally encrypted UDP traffic to be sent in cleartext. This can result in disclosure of sensitive information.
CVE-2026-23563 2 Microsoft, Teamviewer 2 Windows, Digital Employee Experience 2026-06-17 N/A 5.7 MEDIUM
Improper Link Resolution Before File Access (invoked by 1E‑Explorer‑TachyonCore‑DeleteFileByPath instruction) in TeamViewer DEX - 1E Client before version 26.1 on Windows allows a low‑privileged local attacker to delete protected system files via a crafted RPC control junction or symlink that is followed when the delete instruction executes.
CVE-2026-23512 2 Microsoft, Sumatrapdfreader 2 Windows, Sumatrapdf 2026-06-17 N/A 8.6 HIGH
SumatraPDF is a multi-format reader for Windows. In 3.5.2 and earlier, there is a Untrusted Search Path vulnerability when Advanced Options setting is trigger. The application executes notepad.exe without specifying an absolute path when using the Advanced Options setting. On Windows, this allows execution of a malicious notepad.exe placed in the application's installation directory, leading to arbitrary code execution.
CVE-2026-22745 2 Microsoft, Vmware 2 Windows, Spring Framework 2026-06-17 N/A 5.3 MEDIUM
Spring MVC and WebFlux applications are vulnerable to Denial of Service attacks when resolving static resources. More precisely, an application can be vulnerable when all the following are true: * the application is using Spring MVC or Spring WebFlux * the application is serving static resources from the file system * the application is running on a Windows platform When all the conditions above are met, the attacker can send malicious requests that are slow to resolve and that can keep HTTP connections in use. This can cause a Denial of Service on the application.
CVE-2026-21860 2 Microsoft, Palletsprojects 2 Windows, Werkzeug 2026-06-17 N/A 5.3 MEDIUM
Werkzeug is a comprehensive WSGI web application library. Prior to version 3.1.5, Werkzeug's safe_join function allows path segments with Windows device names that have file extensions or trailing spaces. On Windows, there are special device names such as CON, AUX, etc that are implicitly present and readable in every directory. Windows still accepts them with any file extension, such as CON.txt, or trailing spaces such as CON. This issue has been patched in version 3.1.5.
