CVE-2026-32692Network attack vector

Secret poisoning via overbroad Vault token policy

Published Mar 18, 2026 · Updated Mar 18, 2026

Improper authorization in Canonical Juju 3.1.6 through 3.6.18 allows remote authenticated users to overwrite Vault secret revisions. The Vault RestrictedConfig path grants agent tokens create access across the model mount instead of limiting writes to secret identifiers owned by that agent. Exploitation requires an authenticated unit agent and sufficient revision information; successful writes poison existing revisions in the model's Vault back end.
