CVE-2026-59862 – Kiota: Code Generation Literal Injection in the Python Generator

CVE ID :CVE-2026-59862

Published : July 16, 2026, 3:16 p.m. | 18 minutes ago

Description :Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.32.0, Kiota’s Python generator let attacker-controlled enum value descriptions from x-ms-enum.values[].description flow through KiotaBuilder.SetEnumOptions into Documentation.DescriptionTemplate and PythonConventionService.RemoveInvalidDescriptionCharacters without newline sanitization, allowing generated inline comments to split and execute attacker-controlled Python code at module scope when generated modules were imported. This issue is fixed in version 1.32.0.

Severity: 7.5 | HIGH
