Weaponization speed

1 daysto first PoC

Weaponized quickly — attackers prioritized this vulnerability. Patch urgently.

Recommendation: Plan a near-term fix — a public PoC already exists.

All versions of Elastic Cloud Enterprise has the Elasticsearch “anonymous” user enabled by default in deployed clusters. While in the default setting the anonymous user has no permissions and is unable to successfully query any Elasticsearch APIs, an attacker could leverage the anonymous user to gain insight into certain details of a deployed cluster.
