CVE-2026-41134— Kiota 代码注入漏洞

Kiota: Code Generation Literal Injection

Kiota is an OpenAPI based HTTP Client code generator. Versions prior to 1.31.1 are affected by a code-generation literal injection vulnerability in multiple writer sinks (for example: serialization/deserialization keys, path/query parameter mappings, URL template metadata, enum/property metadata, and default value emission). When malicious values from an OpenAPI description are emitted into generated source without context-appropriate escaping, an attacker can break out of string literals and inject additional code into generated clients. This issue is only practically exploitable when the OpenAPI description used for generation is from an untrusted source, or a normally trusted OpenAPI description has been compromised/tampered with. Only generating from trusted, integrity-protected API descriptions significantly reduces the risk. To remediate the issue, upgrade Kiota to 1.31.1 or later and regenerate/refresh existing generated clients as a precaution. Refreshing generated clients ensures previously generated vulnerable code is replaced with hardened output.

对生成代码的控制不恰当(代码注入)

Kiota 代码注入漏洞

Kiota是Microsoft开源的一个OpenAPI客户端代码生成工具。 Kiota 1.31.1之前版本存在代码注入漏洞，该漏洞源于多个写入器接收器存在代码生成字面量注入问题，当恶意值从OpenAPI描述发出到生成的源代码时，可能导致任意代码注入。
