Cisco ThousandEyes BrowserBot Command Injection Vulnerability
A vulnerability in the BrowserBot component of Cisco ThousandEyes Enterprise Agent could have allowed an authenticated, remote attacker to execute arbitrary commands on Agents on behalf of the BrowserBot synthetics orchestration process. Cisco has addressed this vulnerability in the Cisco ThousandEyes Enterprise Agent, and no customer action is needed.
This vulnerability was due to insufficient input validation of command arguments that are supplied by the user. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by authenticating to the ThousandEyes SaaS and submitting crafted input into the affected parameter. A successful exploit could have allowed the attacker to execute arbitrary commands within the BrowserBot container as the node user.
To exploit this vulnerability, the attacker must have valid user credentials for the ThousandEyes SaaS and the ability to manage transaction tests.

CtrlPanel: Unauthenticated RCE using installer script
CtrlPanel is open-source billing software for hosting providers. In versions 1.1.1 and prior, the web-based installer (public/installer/index.php) is vulnerable to unauthenticated Remote Code Execution (RCE) because it performs the install.lock check only after including and executing form handler files, leaving installer endpoints reachable on already-installed instances. The handlers also pass unsanitized user input directly into shell commands, allowing an attacker to submit crafted requests that execute arbitrary commands on the server. The vulnerability stems from two combined weaknesses: (1) premature form handler execution before the lock file gate, and (2) unsafe use of user input in shell command construction. This issue is reported to be actively exploited in the wild. The issue has been fixed in version 1.2.0.

A command injection vulnerability exists in Panabit PAP-XM320 up to and including V7.7. The web management interface invokes the backend helper /usr/sbin/pappiw and passes user-controlled parameters to it. The helper performs unsafe argument processing using eval, which allows command injection when attacker-controlled input is included in the arguments. As a result, an authenticated remote attacker with access to the management interface may execute arbitrary shell commands.

WebdriverIO has Command Injection in the BrowserStack Service
WebdriverIO is a test automation framework for unit, e2e and component testing using WebDriver, WebDriver BiDi and Appium. Versions below 9.24.0 contain a command injection vulnerability leading to remote code execution (RCE) in test orchestration. Git permits branch names containing shell metacharacters, and getGitMetadataForAISelection() interpolates these names directly into execSync() calls without sanitization. An attacker can exploit this by supplying a malicious repository (via testOrchestrationOptions.runSmartSelection.source, or the current directory if unset) whose branch name carries a payload, causing the shell to execute arbitrary code. This enables remote code execution on CI/CD servers and developer machines, leading to credential and secret disclosure, source code and SSH key exfiltration, system compromise, and supply chain attacks via tampered build artifacts. The issue has been fixed in version 9.24.0.

Dokploy has Command Injection in its Service Operations
Dokploy is a free, self-hostable Platform as a Service (PaaS). Versions 0.26.6 and below have OS command injection through the appName parameter. 3 chained issues cause this problem: inadequate input sanitization, lack of schema validation and direct shell interpolation. User-controlled application names are passed through inadequate sanitization (cleanAppName function only replaces spaces and converts to lowercase) before being interpolated directly into shell commands executed via execAsync() and execAsyncRemote(). An authenticated attacker can inject shell metacharacters (e.g., ;, $(), backticks, |, &) in the appName field during application creation, which are then executed with server-level privileges when service operations (start, stop, remove, scale) are triggered. This issue has been resolved in version 0.26.7.

CWE-78 May 15, 2026
Tabby auto-confirms ZMODEM detection on terminal output, leading to shell command execution from displayed file content under fish, bash, and zsh
Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.233, Tabby before 1.0.233 automatically confirms ZMODEM protocol detection on all terminal session output without user interaction, enabling shell command execution when a user displays attacker-controlled content. The ZModemMiddleware in tabby-terminal consumes all session output through a Zmodem.Sentry, and when a ZMODEM ZRQINIT header is detected, unconditionally calls detection.confirm() and writes a fixed ZRINIT response ( **\x18B0100000023be50\r\n\x11) back into the active PTY as input. When the process that triggered the detection (e.g., cat) exits, the injected bytes are consumed by the user's shell as a command line. Under fish (default configuration), the ** prefix triggers recursive glob expansion against the current directory, allowing an attacker-placed executable at a matching nested path (e.g., d/xB0100000023be50) to be executed by relative pathname without relying on PATH. Under bash and zsh, a secondary xterm.js terminal color-query feedback (OSC 10) can be combined in the same file to inject a slash-containing command word that similarly bypasses PATH resolution. An attacker can exploit this by providing a crafted file (e.g., in a cloned Git repository) that a user displays with cat, achieving code execution with no interaction beyond viewing the file. This vulnerability is fixed in 1.0.233.

CWE-78 May 15, 2026
Tabby: RCE via `tabby://run` URL Scheme
Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.233, Tabby registers itself as the handler for the tabby:// URL scheme on all platforms. The URL scheme handler supports a run command that directly executes OS commands with no user confirmation, sanitization, or sandboxing. An attacker can craft a malicious link (tabby://run?command=...) and deliver it via a website, email, chat message, or any other medium. When a victim clicks the link, the OS launches Tabby which immediately spawns the specified command as a child process with the user's full privileges. This is a zero-click-after-link-visit RCE vulnerability. This vulnerability is fixed in 1.0.233.

Vim: Command injection in tar#Vimuntar via missing shellescape {special} flag
Vim is an open source, command line text editor. Prior to 9.2.0479, a command injection vulnerability exists in tar#Vimuntar() in
runtime/autoload/tar.vim when decompressing .tgz archives on Unix-like systems. The function builds :!gunzip and :!gzip -d commands using shellescape(tartail) without the {special} flag, allowing a crafted archive filename to trigger Vim cmdline-special expansion and execute shell commands in the user's context. This vulnerability is fixed in 9.2.0479.

python-utcp: Command Injection via Unsanitized Argument Substitution in CLI Communication Protocol
python-utcp is the python implementation of UTCP. Prior to 1.1.3, the _substitute_utcp_args method in cli_communication_protocol.py inserts user-controlled tool_args values directly into shell command strings without any sanitization or escaping. These commands are then executed via /bin/bash -c (Unix) or powershell.exe -Command (Windows), allowing an attacker to inject arbitrary shell commands. This vulnerability is fixed in 1.1.3.

HRConvert2: Missing Sanitization enables Unauthenticated Remote Command Execution
HRConvert2 is a self-hosted, drag-and-drop & nosql file conversion server & share tool. Prior to 3.3.8, the sanitizeString() function in convertCore.php is missing backtick (`) and tab (\t) from its strip list. User input then reaches shell_exec(), where the shell interprets these characters and commands within filenames execute. This vulnerability is fixed in 3.3.8.

Fleet vulnerable to OS command injection in software packages
Fleet is open source device management software. Prior to version 4.81.0, a vulnerability in Fleet's software installer pipeline could allow a crafted software package to execute arbitrary commands as root (macOS/Linux) or SYSTEM (Windows) on managed endpoints when an uninstall is triggered. When a software package (.pkg, .deb, .rpm, .exe, or .msi) is uploaded to Fleet, metadata is extracted from the package binary and used to generate uninstall scripts. In affected versions, this metadata is not properly sanitized before being included in the generated scripts. A specially crafted package containing malicious values in its metadata fields could result in unintended command execution when the uninstall script runs on managed endpoints. Version 4.81.0 contains a patch. If an immediate upgrade is not possible, administrators should avoid uploading software packages obtained from untrusted or unverified sources. Additionally, administrators can manually inspect and edit auto-generated uninstall scripts before deployment.

Public exploit CWE-78 May 14, 2026
Gotenberg: Unauthenticated RCE via ExifTool Metadata Key Injection
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.31.0, Gotenberg's /forms/pdfengines/metadata/write HTTP endpoint accepts a JSON metadata object and passes its keys directly to ExifTool via the go-exiftool library. No validation is performed on key characters. A \n embedded in a JSON key splits the ExifTool stdin stream into a new argument line, allowing an attacker to inject arbitrary ExifTool flags — including -if, which evaluates Perl expressions. This achieves unauthenticated OS command execution in a single HTTP request. The response is HTTP 200 with a valid PDF, making the attack transparent to basic monitoring. This vulnerability is fixed in 8.31.0.
