CVE-2026-73851
MediumCVSS 6.1Summary
Kiota before versions 1.29.1 and 1.34.0 allows an attacker who controls or tampers with the OpenAPI description to supply a file reference that resolves outside the manifest package (e.g., ../../../../etc/passwd, an absolute path, or a file:// / http(s):// URI). When the generated manifest is deployed and consumed by an AI host, this can lead to inclusion or disclosure of files outside the intended package boundary.
Risk Assessment
The risk includes unauthorized access to system files or external resources, potentially leading to sensitive data leakage or system integrity compromise.
Recommendation
Upgrade Kiota to version 1.29.1 or 1.34.0, which fix this vulnerability.
Original NVD description (English source)
Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.29.1 and 1.34.0, an attacker who controls or tampers with the OpenAPI description consumed by Kiota can supply a file reference that resolves outside the manifest package (e.g. ../../../../etc/passwd, an absolute path, or a file:// / http(s):// URI). When the generated manifest is deployed and consumed by an AI host, this can lead to inclusion or disclosure of files outside the intended package boundary. This vulnerability is fixed in 1.29.1 and 1.34.0.
