A vulnerability was found in douinc mkdocs-mcp-plugin up to 0.4.1. This affects the function readdocument/listdocuments of the file server.py. Performing a manipulation of the argument docsdir/filepath results in path traversal. The attack is possible to be carried out remotely. The exploit has...

PYSEC-2026-2542 kaggle-mcp has a Path Traversal issue

A vulnerability has been found in dexhunter kaggle-mcp up to 406127ffcb2b91b8c10e20e6c2ca787fbc1dc92d. This vulnerability affects the function preparekaggledataset of the file src/kagglemcp/server.py. The manipulation of the argument competitionid leads to path traversal. The attack is possible t...

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-2026-2890 Poetry has Path Traversal in tar extraction on Python 3.10.0 - 3.10.12 and 3.11.0 - 3.11.4

Summary The extractall function in src/poetry/utils/helpers.py:410-426 extracts sdist tarballs without path traversal protection on Python versions where tarfile.datafilter is unavailable. Considering only Python versions which are still supported by Poetry, these are 3.10.0 - 3.10.12 and 3.11.0 ...

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-2026-2943 PraisonAI has Memory State Leakage and Path Traversal in MultiAgent Context Handling

Summary The MultiAgentLedger and MultiAgentMonitor components in the provided code exhibit vulnerabilities that can lead to context leakage and arbitrary file operations. Specifically: 1. Memory State Leakage via Agent ID Collision: The MultiAgentLedger uses a dictionary to store ledgers by agent...

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-2026-2900 PraisonAI recipe registry pull path traversal writes files outside the chosen output directory

Summary PraisonAI's recipe registry pull flow extracts attacker-controlled .praison tar archives with tar.extractall and does not validate archive member paths before extraction. A malicious publisher can upload a recipe bundle that contains ../ traversal entries and any user who later pulls that...

PYSEC-2026-2764 Open WebUI vulnerable to Path Traversal in `POST /api/v1/audio/transcriptions`

Summary An unsanitised filename field in the speech-to-text transcription endpoint allows any authenticated non-admin user to trigger a FileNotFoundError whose message — including the server's absolute DATADIR path — is returned verbatim in the HTTP 400 response body, confirming information...
