CVE-2026-11979 Stack-Based Buffer Overflow in libxml2

libxml2 is vulnerable to multiple stack-based buffer overflows in the xmlcatalog utility when running in --shell mode. The usershell function processes user input using fixed-size stack buffers without proper bounds checking. By supplying an overly long input line, an attacker can overflow intern...

PYSEC-2026-544 MCP-for-Stata: Command injection via log_file_name parameter in Stata command wrapper

Summary The logfilename parameter in the statado API and CLI is directly interpolated into a Stata command string without sanitization. The security guard GuardValidator only scans the do-file content but does not validate this parameter. An attacker can inject arbitrary Stata commands including...

PYSEC-2026-560 utcp-cli Vulnerable to Command Injection via Unsanitized Argument Substitution in CLI Communication Protocol

Summary The substituteutcpargs method in clicommunicationprotocol.py inserts user-controlled toolargs 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...

PYSEC-2026-461 PraisonAI Vulnerable to OS Command Injection

The executecommand function and workflow shell execution are exposed to user-controlled input via agent workflows, YAML definitions, and LLM-generated tool calls, allowing attackers to inject arbitrary shell commands through shell metacharacters. --- Description PraisonAI's workflow system and...

PYSEC-2026-487 PraisonAIAgents has an OS Command Injection via shell=True in Memory Hooks Executor (memory/hooks.py)

Summary The memory hooks executor in praisonaiagents passes a user-controlled command string directly to subprocess.run with shell=True at src/praisonai-agents/praisonaiagents/memory/hooks.py lines 303 to 305. No sanitization, no shlex.quote, no character filter, and no allowlist check exists...

PYSEC-2026-473 PraisonAI has an incomplete fix for CVE-2026-34935 - OS Command Injection

Summary The fix for PraisonAI's MCP command handling does not add a command allowlist or argument validation to parsemcpcommand, allowing arbitrary executables like bash, python, or /bin/sh with inline code execution flags to pass through to subprocess execution. Affected Package - Ecosystem: PyP...

PYSEC-2026-407 Marimo: Pre-Auth Remote Code Execution via Terminal WebSocket Authentication Bypass

Summary Marimo 19.6k stars 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 correct...

PYSEC-2026-477 PraisonAI has critical RCE via `type: job` workflow YAML

praisonai workflow run loads untrusted YAML and if type: job executes steps through JobWorkflowExecutor in jobworkflow.py. This supports: - run: → shell command execution via subprocess.run - script: → inline Python execution via exec - python: → arbitrary Python script execution A malicious YAML...

PYSEC-2026-424 Mlflow: Command Injection when serving models with enable_mlserver=True

A command injection vulnerability exists in Mlflow when serving a model with enablemlserver=True. The modeluri is embedded directly into a shell command executed via bash -c without proper sanitization. If the modeluri contains shell metacharacters, such as $ or backticks, it allows for command...

PYSEC-2026-488 PraisonAI has critical RCE via `type: job` workflow YAML

praisonai workflow run loads untrusted YAML and if type: job executes steps through JobWorkflowExecutor in jobworkflow.py. This supports: - run: → shell command execution via subprocess.run - script: → inline Python execution via exec - python: → arbitrary Python script execution A malicious YAML...

PYSEC-2026-257 AutoGPT bypass of the shell commands denylist settings

A vulnerability in significant-gravitas/autogpt version 0.5.1 allows an attacker to bypass the shell commands denylist settings. The issue arises when the denylist is configured to block specific commands, such as whoami and /bin/whoami. An attacker can circumvent this restriction by executing...

mcp-kubernetes-server has an OS Command Injection vulnerability

feiskyer/mcp-kubernetes-server through 0.1.11 allows OS command injection via the /mcp/kubectl endpoint. The handler constructs a shell command with user-supplied arguments and executes it with subprocess using shell=True, enabling injection through shell metacharacters e.g., ;, &&, $, even when...

InvokeAI Arbitrary File Deletion vulnerability

In invoke-ai/invokeai version v5.0.2, the web API POST /api/v1/images/delete is vulnerable to Arbitrary File Deletion. This vulnerability allows unauthorized attackers to delete arbitrary files on the server, potentially including critical or sensitive system files such as SSH keys, SQLite...

PYSEC-2026-323 DB-GPT Absolute Path Traversal vulnerability

In eosphoros-ai/db-gpt version 0.6.0, the endpoint for uploading files is vulnerable to absolute path traversal. This vulnerability allows an attacker to upload arbitrary files to arbitrary locations on the target server. The issue arises because the filekey and docfile.filename parameters are...

vim: command injection when decompressing .tgz archives

A flaw was found in Vim. When decompressing .tgz archives, the Vimuntar function builds shell commands using shellescape without the special flag. This allows a specially crafted archive filename to trigger Vim cmdline-special expansion and execute arbitrary commands in the context of the current...
