Technical description

Softaculous Virtualizor before 3.2.9 (Patch 9) and 3.0.0 contains an OS command injection vulnerability in the billing module handler that allows unauthenticated remote attackers to execute arbitrary commands as root by bypassing authentication through specific parameter combinations. Attackers can deserialize a crafted billing_data POST field and inject shell payloads through the uid field, which is passed unmodified to proc_open() via vexec(), yielding complete control of the host and all managed VPS instances.

——0A security flaw has been discovered in Moonshot AI Kimi Code up to 0.31.0. The affected element is an unknown function of the file agent-core-v2/src/agent/mcp/config-loader.ts of the component MCP Configuration Loader. The manipulation results in os command injection. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.31.1 is sufficient to fix this issue. It is recommended to upgrade the affected component. Beyond the trust prompt, the fix resolves fd/stty binaries to absolute paths specifically "so untrusted workspaces cannot plant bare-name executables before confirmation," fixing a secondary $PATH path-planting vector alongside the primary untrusted-.mcp.json auto-spawn.1h CVE-2026-852886.7 MED

——0Notepad++ is a free and open-source source code editor. Prior to 8.9.8, Notepad++ incompletely enforces shortcuts.xml HMAC validation because WM_MACRODLGRUNMACRO, the Run a Macro Multiple Times entry point, calls macroPlayback() without the validation used by command(). A tampered shortcuts.xml macro that is blocked through the Macro menu or a shortcut key can therefore execute through the multi-run dialog and invoke internal Notepad++ commands, including commands that launch external programs, in the current user context. This issue is fixed in version 8.9.8.2h CVE-2026-768024.7 MED

——0Nuclei is a vulnerability scanner built on a simple YAML-based DSL. From 3.0.0 until 3.10.0, the DAST template loading branch does not apply the unsigned code-template signature check before accepting a template that contains both a fuzzing: block and an unsigned code: block. When an operator enables -dast, an untrusted multiprotocol template can place an unsigned code request into the execution queue and run arbitrary shell commands even without -code or a valid cryptographic signature. The issue affects CLI DAST scans and SDK integrations that enable DAST while accepting attacker-supplied templates. This issue is fixed in version 3.10.0.3h CVE-2026-801529.1 CRI

——0Lantronix SLC8000 before firmware v9.7.0.3, EMG8500/EMG7500 before firmware v9.7.0.1, and all firmware versions of SLB882/SLCx-03/SLCx-02 contain a command injection vulnerability that allows authenticated attackers with the services permission to execute arbitrary shell commands as root by exploiting the set script schedule command that passes unsanitized user input to a system() call. Attackers with the services permission can authenticate to the terminal or CLI interface and inject malicious commands through the unsanitized parameter to achieve complete loss of confidentiality, integrity, and availability on the affected device and potentially impact downstream serial-attached devices.4h CVE-2026-801519.1 CRI
