PYSEC-2026-2893 PPTAgent: Arbitrary File Write + Directory Creation via markdown_table_to_image

Summary The markdowntabletoimage tool accepts a caller-controlled path parameter and passes it directly to gethtmltableimage: python pptagent/mcpserver.py:127-143 def markdowntabletoimagemarkdowntable: str, path: str, css: str - str: """ Args: path str: The file path where the image will be saved...

PYSEC-2026-2894 PPTAgent: Arbitrary File Write via `save_generated_slides`

Summary This vulnerability has been fixed in https://github.com/icip-cas/PPTAgent/commit/418491a9a1c02d9d93194b5973bb58df35cf9d00. The savegeneratedslides MCP tool accepts a pptxpath argument and writes the generated PPTX file to that path without any workspace restriction or path validation:...

PYSEC-2026-3426 wireshark-mcp vulnerable to arbitrary file write via export_objects when WIRESHARK_MCP_ALLOWED_DIRS is not configured

Description Impact wireshark-mcp exposes a wiresharkexportobjects MCP tool that accepts an attacker-controlled destdir parameter and passes it to tshark's --export-objects flag with no mandatory path restriction. The path sandbox alloweddirs is None by default and only activates when the...

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-2026-2949 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-2026-2922 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-2026-2545 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-2026-2989 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...

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...
