SCA: security update for fastapi-code-generator (GHSA-6xmv-cjr5-w3q8)

critical Tenable Self-Hosted Container Security Plugin ID 478838

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 an additional response status-code key into the generated responses={...} route-decorator
 dictionary as a single-quoted Python string without escaping embedded quotes. A multi-response OpenAPI
 operation with an attacker-controlled or attacker-influenced second non-primary response key can close the
 dictionary-key literal and inject a valid Python expression. Syntax-breaking input only causes generation
 to fail, but syntactically valid generated code executes with the application's or CI process's privileges
 when the generated module is imported and its decorator arguments are evaluated. This additional-response-
 key sink is distinct from the project's separate route-path and operation-summary sinks. This issue is
 fixed in version 0.8.1. (CVE-2026-63469)

Solution

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