PYSEC-2026-2599 LiteLLM: Authenticated command execution via MCP stdio test endpoints

Impact Two endpoints used to preview an MCP server before saving it — POST /mcp-rest/test/connection and POST /mcp-rest/test/tools/list — accepted a full server configuration in the request body, including the command, args, and env fields used by the stdio transport. When called with a stdio...

PYSEC-2026-2521 InstructLab vulnerable to Path Traversal

A flaw was found in InstructLab. A local attacker could exploit a path traversal vulnerability in the chat session handler by manipulating the logsdir parameter. This allows the attacker to create new directories and write files to arbitrary locations on the system, potentially leading to...

PYSEC-2026-2914 PraisonAI Vulnerable to RCE via Automatic tools.py Import

PraisonAI automatically imports ./tools.py from the current working directory when launching certain components. This includes call.py, toolresolver.py, and CLI tool-loading paths. A malicious tools.py placed in the process working directory is executed immediately, allowing arbitrary Python code...

PYSEC-2026-2947 PraisonAI Vulnerable to RCE via Automatic tools.py Import

PraisonAI automatically imports ./tools.py from the current working directory when launching certain components. This includes call.py, toolresolver.py, and CLI tool-loading paths. A malicious tools.py placed in the process working directory is executed immediately, allowing arbitrary Python code...

PYSEC-2026-2949 PraisonAIAgents: Arbitrary File Read via read_skill_file Missing Workspace Boundary and Approval Gate

Summary readskillfile in skilltools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skillpath parameter. Unlike filetools.readfile which enforces workspace boundary confinement, and unlike runskillscript which requires critical-level approval, readskillfile has...

PYSEC-2026-2895 PraisonAI Vulnerable to Implicit Execution of Arbitrary Code via Automatic `tools.py` Loading

PraisonAI automatically loads a file named tools.py from the current working directory to discover and register custom agent tools. This loading process uses importlib.util.specfromfilelocation and immediately executes module-level code via spec.loader.execmodule without explicit user consent,...

PYSEC-2026-2917 PraisonAI has Template Injection in Agent Tool Definitions

Summary Direct insertion of unescaped user input into template-rendering tools allows arbitrary code execution via specially crafted agent instructions. Details The createagentcentrictools function returns tools like acpcreatefile that process file content using template rendering. When user inpu...

PYSEC-2026-2613 Lupa has a Sandbox escape and RCE due to incomplete attribute_filter enforcement in getattr / setattr

Summary The attributefilter in the Lupa library is intended to restrict access to sensitive Python attributes when exposing objects to Lua. However, the filter is not consistently applied when attributes are accessed through built-in functions like getattr and setattr. This allows an attacker to...

PYSEC-2026-2922 PraisonAI recipe registry publish path traversal allows out-of-root file write

Summary PraisonAI's recipe registry publish endpoint writes uploaded recipe bundles to a filesystem path derived from the bundle's internal manifest.json before it verifies that the manifest name and version match the HTTP route. A malicious publisher can place ../ traversal sequences in the bund...

PYSEC-2026-2989 pyLoad: Unprotected storage_folder enables arbitrary file write to Flask session store and code execution (Incomplete fix for CVE-2026-33509)

Summary The fix for CVE-2026-33509 GHSA-r7mc-x6x7-cqxx added an ADMINONLYOPTIONS set to block non-admin users from modifying security-critical config options. The storagefolder option is not in this set and passes the existing path restriction because the Flask session directory is outside both...

PYSEC-2026-2545 kedro-datasets has a path traversal vulnerability in PartitionedDataset that allows arbitrary file write

Impact PartitionedDataset in kedro-datasets was vulnerable to path traversal. Partition IDs were concatenated directly with the dataset base path without validation. An attacker or malicious input containing .. components in a partition ID could cause files to be written outside the configured...

PYSEC-2026-2899 PraisonAI Has Arbitrary File Write (Zip Slip) in Templates Extraction

The PraisonAI templates installation feature is vulnerable to a "Zip Slip" Arbitrary File Write attack. When downloading and extracting template archives from external sources e.g., GitHub, the application uses Python's zipfile.extractall without verifying if the files within the archive resolve...

PYSEC-2026-2327 Azure Data Explorer MCP Server: KQL Injection in multiple tools allows MCP client to execute arbitrary Kusto queries

Summary adx-mcp-server ListDictstr, Any: client = getkustoclient query = f"tablename | getschema" ListDictstr, Any: client = getkustoclient query = f"tablename | sample samplesize" ListDictstr, Any: client = getkustoclient query = f".show table tablename details" -- KQL injection resultset =...

PYSEC-2026-2996 pyLoad SETTINGS Permission Users Can Achieve Remote Code Execution via Unrestricted Reconnect Script Configuration

Summary The setconfigvalue API endpoint allows users with the non-admin SETTINGS permission to modify any configuration option without restriction. The reconnect.script config option controls a file path that is passed directly to subprocess.run in the thread manager's reconnect logic. A SETTINGS...

PYSEC-2026-2693 Open WebUI has unauthorized deletion of knowledge files

Summary An access control check is missing when deleting a file from a knowledge base. The only check being done is that the user has write access to the knowledge base or is admin, but NOT that the file actually belongs to this knowledge base. It is thus possible to delete arbitrary files from...

PYSEC-2026-3001 PyMuPDF has a path traversal in _main_.py

A path traversal and arbitrary file write vulnerability exist in the embedded get function in 'main.py' in PyMuPDF version, 1.26.5...

PYSEC-2026-2656 Arbitrary file write via tar traversal in mlflow

A vulnerability in MLflow's pyfunc extraction process allows for arbitrary file writes due to improper handling of tar archive entries. Specifically, the use of tarfile.extractall without path validation enables crafted tar.gz files containing .. or absolute paths to escape the intended extractio...

PYSEC-2026-3030 PySpector has a Plugin Sandbox Bypass leads to Arbitrary Code Execution

Summary PySpector versions = 0.1.6 are affected by a security validation bypass in the plugin system. The validateplugincode function in pluginsystem.py, performs static AST analysis to block dangerous API calls before a plugin is trusted and executed. However, the internal resolvename helper onl...

PYSEC-2026-2856 OpenViking contains a Path Traversal vulnerability

OpenViking versions 0.2.1 and prior, fixed in commit 46b3e76, contain a path traversal vulnerability in the .ovpack import handling that allows attackers to write files outside the intended import directory. Attackers can craft malicious ZIP archives with traversal sequences, absolute paths, or...

PYSEC-2026-3047 RAGAS has an Arbitrary File Read vulnerability

An Arbitrary File Read vulnerability exists in the ImageTextPromptValue class in Exploding Gradients RAGAS v0.2.3 to v0.2.14. The vulnerability stems from improper validation and sanitization of URLs supplied in the retrievedcontexts parameter when handling multimodal inputs...
