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: NuGet: Microsoft.OpenApi.Kiota, NuGet: Microsoft.OpenApi.Kiota.Builder

### Impact

When generating an API plugin manifest from an attacker-controlled or compromised OpenAPI description, Kiota copies `x-ai-capabilities.response_semantics.oauth_card_path` into the manifest without validating that it is a safe package-relative file reference. An attacker can supply parent-directory traversal, rooted paths, or absolute URIs instead of a card file within the plugin package.

The unsafe reference is propagated into the generated manifest. Its security effect depends on the downstream host's handling of the reference when the plugin is packaged and deployed. This is not local code execution or a file read performed by Kiota merely during generation. A consuming host that resolves the untrusted reference can cross the intended package boundary or use an unintended authentication card.

### Affected versions

The affected NuGet packages are `Microsoft.OpenApi.Kiota` and `Microsoft.OpenApi.Kiota.Builder`, starting with version 1.25.1, which introduced this manifest field. The field remains unvalidated through version 1.34.1, including the separate 1.29.1 security-backport release. Version 1.35.0 fixes the issue.

### Patches

Upgrade to Kiota 1.35.0 or later and regenerate affected plugin manifests. Kiota now applies the existing safe-file-reference validator to `oauth_card_path`, drops unsafe references, and emits a warning. Valid relative card paths remain supported.
