Published Jul 16, 2026 CVSS 9.3

Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.32.5, kiota plugin add and kiota plugin generate (with -t APIPlugin) emitted attacker-controlled static_template.file values from x-ai-adaptive-card and x-ai-capabilities into generated Microsoft 365 Copilot and Teams plugin manifests without path validation, allowing ../, absolute, rooted, UNC, Windows drive, or URI paths in response_semantics.static_template.file to cause path traversal or out-of-package file inclusion when the generated plugin was deployed. This issue is fixed in version 1.32.5.
