CVE-2026-105795: Microsoft Kiota
Low severity, CVSS 3.1. EPSS: 1.2% chance of exploitation in the next 30 days.
Kiota is an OpenAPI based HTTP Client code generator. From 1.25.1 until 1.35.0, Kiota copies x-ai-capabilities.response_semantics.oauth_card_path from an attacker-controlled or compromised OpenAPI description into a generated API plugin manifest without validating that the value is a safe package-relative file reference. Parent-directory traversal, rooted paths, or absolute URIs can therefore reach a consuming host that resolves the reference, allowing the host to cross the intended plugin-package boundary or use an unintended authentication card. Kiota does not itself read a local file or execute code merely while generating the manifest, and impact requires downstream resolution of the unsafe reference. This issue is fixed in version 1.35.0.
Affected products
- Microsoft Kiota: from 1.25.1, before 1.35.0 (fixed in 1.35.0)
- Microsoft Microsoft.openapi.kiota: from 1.25.1, before 1.35.0 (fixed in 1.35.0)
- Microsoft Microsoft.openapi.kiota.builder: from 1.25.1, before 1.35.0 (fixed in 1.35.0)
