CVE-2026-59865

Kiota: Command injection via x-ms-kiota-info dependencyInstallCommand surfaced by `kiota info`

State: Published
Severity: 9.3 Critical
Published: Jul 16, 2026
Updated: Aug 17, 2026
Reserved: Jul 7, 2026

Description

Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.29.1 and 1.32.5, `kiota info` read x-ms-kiota-info.languagesInformation.<language>.dependencyInstallCommand plus dependency name and version values from an OpenAPI description and presented the spec-supplied command as Kiota's recommended install command, allowing an attacker-controlled or compromised description to cause command injection when the suggested command was run manually or through the Kiota VS Code extension's kiota info --json dependency-install flow. This issue is fixed in version 1.29.1 and 1.32.5.
