CVE-2026-73851 | BDVDB-2026-360644 Detail
Microsoftkiota
Description#
Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.29.1 and 1.34.0, an attacker who controls or tampers with the OpenAPI description consumed by Kiota can supply a file reference that resolves outside the manifest package (e.g. ../../../../etc/passwd, an absolute path, or a file:// / http(s):// URI). When the generated manifest is deployed and consumed by an AI host, this can lead to inclusion or disclosure of files outside the intended package boundary. This vulnerability is fixed in 1.29.1 and 1.34.0.
Impact#
Per CVSS v4.0: confidentiality impact none, integrity impact none, availability impact none. Attack vector: network.
