CRITICALPre-NVD 9.39.3
EchelonGraph scoreLOW confidence

This critical-severity CVE scores 9.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.32.5, kiota info read x-ms-kiota-info.languagesInformation..dependencyInstallCommand plus dependency name and version values from an OpenAPI description and presented the spec-supplied command as Kiota's recommended install command, allowing an attacker-controlled or compromised description to cause command injection when the suggested command was run manually or through the Kiota VS Code extension's kiota info --json dependency-install flow. This issue is fixed in version 1.32.5.
