CVE-2026-30968

What it is

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.
