GHSA-P5RM-JG5C-8C77 Microsoft Kiota: Path traversal in generated plugin manifest static_template.file reference (percent-encoding bypass)

Impact Kiota generates AI plugin manifests from an OpenAPI description. When the description contains an x-ai-capabilities response semantics statictemplate or the adaptive-card extension x-ai-adaptive-card, the file reference is written into the generated manifest's...

GHSA-4VV7-JJ25-4GH6 Microsoft Kiota: Arbitrary file write + code-injection via x-ms-kiota-info clientClassName and clientNamespaceName

Summary Microsoft Kiota emitted the x-ms-kiota-info extension's clientClassName or clientNamespaceName value raw, with no identifier or path sanitization, as both the generated client's class/namespace name and part of the generated output path. When kiota generate is run without -c/--class-name ...

GHSA-4RJ6-VRWV-WR8M Microsoft Kiota Workspace-config poisoning: out-of-repo file write + generation-time SSRF

Summary Microsoft Kiota honors a poisoned .kiota/workspace.json — the workspace configuration that Kiota's documented team workflow has developers commit to their repository — unvalidated on kiota client generate / kiota plugin generate. A repository or pull request containing a malicious...

GHSA-RG4H-FPCP-2QM8 Microsoft Kiota: Generation-time SSRF + remote/local file inclusion via unrestricted $ref

Summary Microsoft Kiota resolved OpenAPI $refs by fetching remote https URLs and reading local files including absolute / out-of-tree paths, inlining the referenced schema into the generated client. Running kiota generate on a spec whose $ref pointed at an attacker/internal URL or an arbitrary...

GHSA-4JWF-M4WG-8P66 Microsoft Kiota: Path/URL injection into generated Copilot plugin manifest via x-ai-* extensions

Summary kiota plugin add / kiota plugin generate with -t APIPlugin emits an attacker-controlled statictemplate.file path from the AI-plugin extensions x-ai-adaptive-card, x-ai-capabilities verbatim, with no path validation, into the generated Microsoft 365 Copilot / Teams plugin manifest...
