High CVSS 7

CVE-2026-59863

Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.32.5, Kiota honored a poisoned .kiota/workspace.json workspace configuration without validating per-client or per-plugin outputPath values during kiota client generate and kiota plugin generate, allowing a malicious repository or pull request to use absolute paths, rooted POSIX / paths, UNC \\ or // paths, Windows drive X:\ paths, or .. traversal segments to write generated client files outside the workspace root on a developer or CI host. This issue is fixed in version 1.32.5.

What this means

Exposure
Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
Impact
An attacker can read some data, modify or destroy data and degrade the service.
Weakness
An attacker-supplied file path is not confined, letting them read or write outside the intended folder.
Likelihood
Its EPSS score puts short-term exploitation in a middle band: neither negligible nor imminent.
