NewCVE-2026-107377 (opens in a new tab)How to fix?
Upgrade datamodel-code-generator to version 0.81.0 or higher.
Overview
datamodel-code-generator is a Datamodel Code Generator
Affected versions of this package are vulnerable to External Control of File Name or Path via the _write_missing_weak_imports method in src/datamodel_code_generator/parser/protobuf.py when processing a Protocol Buffers schema file containing a weak import directive. An attacker who controls the input schema can supply a weak import path containing directory traversal sequences (e.g. ../../) that cause the parser to write arbitrary stub files outside the intended temporary directory, resulting in unauthorized file writes to the filesystem.
