SCA: security update for datamodel-code-generator (GHSA-77xj-x4rm-935c)

high Tenable Cloud Security Plugin ID 473877

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - datamodel-code-generator generates Python data models from schema definitions. From 0.59.0 until 0.81.0,
 an attacker-controlled Protobuf schema can supply absolute or parent-directory paths captured by
 WEAK_IMPORT_PATTERN and consumed by _write_missing_weak_imports in
 src/datamodel_code_generator/parser/protobuf.py. Exploitation requires a victim or automated job to
 process the attacker-controlled schema with Protobuf input support, which requires the grpcio-tools
 package. The paths escape the weak_imports temporary directory before protoc runs, allowing creation of
 directory trees and new files or overwrite of existing writable files with a generated Protobuf syntax
 declaration. The effect persists when later Protobuf compilation fails. The written content is limited to
 a proto2 or proto3 syntax declaration, and direct arbitrary code execution has not been demonstrated. This
 issue is fixed in version 0.81.0. (CVE-2026-107377)

Solution

Update the datamodel-code-generator library and its related packages to version 0.81.0 or later.
