Threats affecting pkg:github/coral-protocol/coral-server

Coral Server is open collaboration infrastructure that enables communication, coordination, trust and payments for The Internet of Agents. Prior to 1.1.0, Coral Server allowed the creation of agent sessions through the /api/v1/sessions endpoint without strong authentication. This endpoint performs resource-intensive initialization operations including container spawning and memory context creation. An attacker capable of accessing the endpoint could create sessions or consume system resources without proper authorization. This vulnerability is fixed in 1.1.0.

CVE-2026-30969 is a high-severity authorization bypass vulnerability in Coral-Protocol's coral-server versions prior to 1.1.0. The flaw arises from insufficient authentication enforcement between agents and the server during active sessions, allowing attackers who obtain or predict session identifiers to impersonate agents or join existing sessions. Exploitation requires network access and low privileges but no user interaction. This vulnerability impacts confidentiality and integrity by enabling unauthorized access and potential manipulation of agent communications. The issue is fixed in version 1.1.0. Organizations using coral-server versions before 1.

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.
