CVE-2026-61783: RBAC flaw in Wazuh Manager exposes cluster.key, the secret that authenticates inter-node cluster traffic. The masking check only looks for a config-update RBAC rule, not whether it allows or denies the action. Attaching a deny rule is enough to get the raw key back from the config API. Patched in v4.14.7 and v5.0.0-beta3. Found by a CyStack researcher.
