An attacker can supply parent-directory traversal, rooted paths, or absolute URIs instead of a card file within the plugin package.\n\nThe 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.\n\n### Affected versions\n\nThe 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.\n\n### Patches\n\nUpgrade 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.\n\n- Fix: https://github.com/microsoft/kiota/pull/8055\n- Fixed release: https://github.com/microsoft/kiota/releases/tag/v1.35.0\n\n### Workarounds\n\nGenerate plugins only from trusted, integrity-protected OpenAPI descriptions. Before packaging or deployment, review generated manifests and remove any `oauth_card_path` that is not a safe relative reference confined to the plugin package. Do not rely on validation of sibling manifest fields to validate this field.\n\n### Related advisories\n\nGHSA-4jwf-m4wg-8p66 and GHSA-p5rm-jg5c-8c77 cover `static_template.file`. Their fixes do not enforce validation at the separate `oauth_card_path` emission site.","state":0,"publishedAt":"2026-10-06T15:36:13+00:00","modifiedAt":"2026-10-06T15:46:43.0927233+00:00","affected":[{"ecosystem":"NuGet","name":"Microsoft.OpenApi.Kiota","ranges":[{"type":"ECOSYSTEM","events":[{"kind":"introduced","version":"1.25.1"},{"kind":"fixed","version":"1.35.0"}]}],"versions":["1.25.1","1.26.0","1.26.1","1.27.0","1.28.0","1.29.0","1.29.1","1.30.0","1.31.0","1.31.1","1.32.0","1.32.1","1.32.2","1.32.3","1.32.4","1.32.5","1.33.0","1.34.0","1.34.1"],"rawVersionEvidence":null},{"ecosystem":"NuGet","name":"Microsoft.OpenApi.Kiota.Builder","ranges":[{"type":"ECOSYSTEM","events":[{"kind":"introduced","version":"1.25.1"},{"kind":"fixed","version":"1.35.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/microsoft/kiota/security/advisories/GHSA-6gw6-rv2g-25mg","https://nvd.nist.gov/vuln/detail/CVE-2026-105795","https://github.com/microsoft/kiota/pull/8055","https://github.com/microsoft/kiota/commit/fc0f219b8a665c4c69be8befcff035ba0eb8e4ce","https://github.com/microsoft/kiota","https://github.com/microsoft/kiota/releases/tag/v1.35.0"],"sourceUrl":"https://github.com/advisories/GHSA-6gw6-rv2g-25mg","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-6gw6-rv2g-25mg","identifiers":["GHSA-6gw6-rv2g-25mg","CVE-2026-105795"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
