CVE-2026-116243
pgAdmin 4 runs pg_dump, pg_restore, pg_dumpall and psql from the binary path a user sets in their preferences. In server mode the binary path was refused only when it lay under the per-user storage directory (STORAGE_DIR), not under a SHARED_STORAGE directory, which ordinary users can upload files to. A user could therefore upload an executable to shared storage, point their binary path at it, and have pgAdmin run it as the operating-system account running pgAdmin. On POSIX, files created through pgAdmin are not executable, so this is exploitable where any file with an executable name can run, such as Windows server mode. The fix checks the binary path against every SHARED_STORAGE directory as well, after expanding $DIR, collapsing ".." and resolving symbolic links, compares directories in a way a different spelling on a case-insensitive filesystem cannot bypass, refuses a path containing a NUL, and enforces the check wherever binary paths are resolved, including for the PSQL tool. This issue affects pgAdmin 4: before 9.19.

When the installer is launched in a directory containing a specially crafted DLL file, the malicious DLL may be loaded, resulting in arbitrary code execution with administrative privileges.
-
CVE-2025-54991
JupyterLab Desktop is the cross-platform desktop application for JupyterLab. Prior to 4.6.2-1, JupyterLab Desktop for macOS declared the com.apple.security.cs.allow-dyld-environment-variables entitlement, allowing the dynamic linker to honor DYLD_INSERT_LIBRARIES despite the hardened runtime. An attacker who can already execute code as the current user can load an arbitrary dynamic library into the JupyterLab Desktop process and inherit TCC permissions previously granted to the application, including access to protected Documents, Desktop, or Downloads folders without another macOS prompt. Exploitation requires existing local code execution and prior TCC grants; it does not provide initial or remote code execution. Windows and Linux are not affected. This vulnerability is fixed in 4.6.2-1.

CVE-2026-62848
Metalama is a Roslyn-based open-source patterns and architecture toolkit for C#. From 2023.0.101-rc until 2025.1.18, 2026.0.25 and 2026.1.19, the Windows Visual Studio integration deserializes local named-pipe messages without restricting which CLR types can be instantiated. The pipe connects `devenv`, the out-of-process Roslyn code-analysis process and the `CodeLens` process, and has the predictable name `Metalama_{role}_{processId}_{hash(PackageVersion)}`. Releases from the first public 2023.0 line through 2026.0.x use Newtonsoft.Json with `TypeNameHandling.All`; the later `SerializationBinder` only remaps assembly names, and `BindToType` resolves arbitrary wire-supplied types without an allow-list. Releases 2026.1.0 through 2026.1.18 use typeless MessagePack with `TypelessObjectResolver` and likewise instantiate arbitrary types. A same-user local process able to write to the pipe can send crafted messages that lead to arbitrary code execution with confidentiality, integrity and availability impacts inside the affected Visual Studio process. Default Windows pipe ACLs limit writers to the same logged-in user, so this does not escalate privileges or cross a security boundary; command-line and MSBuild-only builds do not use the channel. The maintained Metalama + PostSharp extension is affected from 2024.1 through 2026.1.4, while earlier Metalama-free PostSharp versions are unaffected. The retired Metalama and Caravela extensions remain affected and require removal or migration. The framework issue is fixed in versions 2025.1.18, 2026.0.25 and 2026.1.19; the maintained Metalama + PostSharp Visual Studio extension is fixed in version 2026.1.5. The retired Metalama and Caravela extensions require removal or migration.

-
CVE-2026-40573
NovumOS is a custom 32-bit operating system written in Zig and x86 Assembly. Prior to version 0.25-beta.1, the `Nova` interpreter runs in Ring 0 with unrestricted kernel-memory access. Loading a malicious `.nv` script through the shell permits a local user to execute code with kernel privileges without security checks. The advisory identifies VM initialization in `zig/nova/vm.zig` as the affected component; script execution is not isolated in a restricted Ring 3 privilege domain. This issue is fixed in version 0.25-beta.1.

CVE-2026-101309
The xHCI (USB 3) device model did not validate or save the event ring size provided by the guest. The size was re-read from guest memory on each use, and Transfer Request Block (TRB) fields were loaded without protection against concurrent modification by the guest. This race condition could be triggered by a guest running malicious, privileged code. A malicious guest can crash the bhyve process or potentially execute arbitrary code in the host userspace context running the virtual machine, subject to bhyve's Capsicum sandbox.
-
CVE-2026-101311
The framebuffer device model's maximum resolution constants were duplicated between the framebuffer and RFB modules and had gotten out of sync. Additionally, writes to the framebuffer BAR could set arbitrary width and height values without validation, and the framebuffer BAR I/O and RFB rendering threads were not synchronized. A malicious guest can crash the bhyve process or potentially execute arbitrary code in the host userspace context running the virtual machine, subject to bhyve's Capsicum sandbox.

CVE-2026-119193
PHPUnit is a testing framework for PHP. From 13.4.0 until 13.4.4, the TestCase::coverageFilesDirectory() logic in src/Runner/Phpt/TestCase.php creates temporary files for PHPT code coverage in a predictable phpunit-phpt directory under sys_get_temp_dir() and reuses that directory without verifying its ownership or permissions. On multi-user systems with a shared temporary path, a local attacker who creates the directory before the developer runs PHPT tests with code coverage can replace the generated job file before the child process executes it with require, allowing arbitrary code execution with the developer's privileges while the test and coverage report appear successful. PHPUnit 12.5 and earlier, default macOS and Windows configurations with per-user temporary directories, and single-user environments where another user cannot create files in the temporary path are not affected. This issue is fixed in 13.4.4.
