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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-105795)\n\nAffected packages:\n\n- `Microsoft.OpenApi.Kiota >= 1.25.1, < 1.35.0`\n- `Microsoft.OpenApi.Kiota.Builder >= 1.25.1, < 1.35.0`\n\nPatched in:\n\n- `Microsoft.OpenApi.Kiota 1.35.0`\n- `Microsoft.OpenApi.Kiota.Builder 1.35.0`\n\nSource: https://github.com/advisories/GHSA-6gw6-rv2g-25mg","depth":"sunlit","depthScore":17,"depthScoreParts":{"impact":17.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
