SCA: security update for fastapi-code-generator (GHSA-h667-4jj2-cgv4)

critical Tenable Self-Hosted Container Security Plugin ID 478833

Description

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

 - fastapi-code-generator creates FastAPI applications from OpenAPI files. Prior to 0.8.1, the generator
 inserts Operation.summary into a generated route-handler docstring as a triple-double-quoted string
 without escaping embedded triple quotes. An attacker-controlled or attacker-influenced operation summary
 can close the docstring and inject a valid Python expression statement into the handler body. Syntax-
 breaking input only causes generation to fail, but syntactically valid generated code executes with the
 server process's privileges when the affected route handler is called. This call-time route-handler
 docstring sink is distinct from the project's separate import-time route-path and additional-response-key
 sinks. This issue is fixed in version 0.8.1. (CVE-2026-63470)

Solution

Update the fastapi-code-generator library and its related packages to version 0.8.1 or later.
