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":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"microsoft","product":"kiota","versions":[{"version":">= 1.25.1, < 1.35.0","status":"affected"}]},{"vendor":"microsoft","product":"Microsoft.OpenApi.Kiota","versions":[{"version":">= 1.25.1, < 1.35.0","status":"affected"}]},{"vendor":"microsoft","product":"Microsoft.OpenApi.Kiota.Builder","versions":[{"version":">= 1.25.1, < 1.35.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","baseScore":3.1,"baseSeverity":"LOW","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":1.6,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-06T17:17:41.953926Z","id":"CVE-2026-105795","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"}]}],"references":[{"url":"https://github.com/microsoft/kiota/commit/fc0f219b8a665c4c69be8befcff035ba0eb8e4ce","source":"security-advisories@github.com"},{"url":"https://github.com/microsoft/kiota/pull/8055","source":"security-advisories@github.com"},{"url":"https://github.com/microsoft/kiota/releases/tag/v1.35.0","source":"security-advisories@github.com"},{"url":"https://github.com/microsoft/kiota/security/advisories/GHSA-6gw6-rv2g-25mg","source":"security-advisories@github.com"}]}
