How severe is CVE-2026-59865?
CVE-2026-59865 is rated Critical with a CVSS score of 9.3. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

What should I do about CVE-2026-59865?
Upgrade Kiota to 1.32.5 and avoid running install commands from untrusted specs
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Attacker-controlled OpenAPI spec can inject shell commands via kiota info or VS Code dependency-install, enabling arbitrary command execution on dev machines/CI.
Immediate action required
- affected>= 1.30.0 and < 1.31.1
- affected< 1.29.1
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
