GHSA-RPJ2-4HQ8-938G VCR.py: Arbitrary code execution via unsafe YAML deserialization of cassette files

Summary vcrpy deserializes YAML cassette files with PyYAML's object-constructing loader yaml.CLoader / yaml.Loader instead of the safe loader yaml.CSafeLoader / yaml.SafeLoader. A cassette containing a !!python/object/apply: or similar tag therefore executes arbitrary Python code the moment the...

GHSA-JWM3-QCFW-C5PP n8n: Python Code Node AST Validator Bypass

Impact An authenticated user with permission to create or modify workflows containing a Python Code node could bypass the AST security validator and access the task executor module namespace. On self-hosted instances where N8NBLOCKRUNNERENVACCESS=false is set, this extended to disclosure of...

Arbitrary Code Execution

Overview n8n is a n8n Workflow Automation Tool Affected versions of this package are vulnerable to Arbitrary Code Execution in the Python Code node, exploitable when the Python Task Runner is enabled. A user with permission to create or modify workflows can execute arbitrary code on the task runn...
