Vulnerability details
CVE-2026-30968
Coral-Protocol coral-server
Coral Server has insufficient validation of agent identity for SSE connections
CVSS 4.0
8.6High
Official description
Coral Server is open collaboration infrastructure that enables communication, coordination, trust and payments for The Internet of Agents. Prior to 1.1.0, the SSE endpoint (/sse/v1/...) in Coral Server did not strongly validate that a connecting agent was a legitimate participant in the session. This could theoretically allow unauthorized message injection or observation. This vulnerability is fixed in 1.1.0.
