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...

Bugsink affected by authenticated arbitrary file write in artifactbundle/assemble

Authenticated arbitrary file write in artifact bundle assembly SummaryAn authenticated file write vulnerability was identified in Bugsink 2.1.0 in the artifact bundle assembly flow.A user with a valid authentication token could cause the application to write attacker-controlled content to a...

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

SummaryPraisonAI'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 bundl...

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-2026-2545 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 recipe registry pull path traversal writes files outside the chosen output directory

SummaryPraisonAI'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...

Open WebUI's process_files_batch() endpoint missing ownership check, allows unauthorized file overwrite

SummaryAny authenticated user can overwrite any file's content by ID through the POST /api/v1/retrieval/process/files/batch endpoint. The endpoint performs no ownership check, so a regular user with read access to a shared knowledge base can obtain file UUIDs via GET /api/v1/knowledge/id/files an...

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...

OpenViking contains a Path Traversal vulnerability

OpenViking versions 0.2.1 and prior, fixed in commit46b3e76, 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...

BentoML Vulnerable to Arbitrary File Write via Symlink Path Traversal in Tar Extraction

Arbitrary File Write via Symlink Path Traversal in Tar Extraction SummaryThe safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a...
