CVE-2026-30968
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCoral 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Coral Server SSE endpoint (/sse/v1/...) prior to version 1.1.0 lacked strong validation to verify that connecting agents were legitimate session participants. This authentication/authorization gap in the Server-Sent Events real-time communication channel could allow unauthorized actors to inject malicious messages into streams or observe sensitive event data intended for other agents.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Coral Server installationLocate the Coral Server installation and determine its version number. Common methods include checking the server's about/status endpoint, examining installed package files, or querying the service directly.Affected if The installed version is less than 1.1.0 (e.g., 1.0.x, 0.x.x)
-
Verify SSE endpoint availabilityConfirm that the Server-Sent Events endpoint at /sse/v1/... is accessible on the Coral Server. This can be done by reviewing the server's exposed routes or attempting a connection to the endpoint.Affected if The SSE endpoint is exposed and reachable without additional authentication checks
-
Check SSE endpoint authentication configurationExamine the Coral Server configuration files or API settings related to the /sse/v1/ endpoint. Look for authentication, authorization, or session validation settings specific to the SSE channel.Affected if The SSE endpoint lacks strong session participant validation or token verification for incoming connections
-
Inspect network exposure of SSE channelReview network access controls, firewall rules, or API gateway settings to determine if the SSE endpoint is accessible from untrusted networks or external clients.Affected if The SSE endpoint is exposed to networks where unauthorized agents could connect
A system is affected if it runs Coral Server version below 1.1.0 with the SSE endpoint at /sse/v1/... exposed and lacking proper session participant validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.1.0
Upgrade to Coral Server version 1.1.0 or later. If immediate upgrade is not possible, implement additional session token validation and origin checking on the SSE endpoint as a compensating control.
1.1.0
- Identify the current version of Coral Server being used
- Stop the Coral Server service
- Upgrade Coral Server to version 1.1.0 or later
- Verify the upgrade was successful by checking the version number
- Restart the Coral Server service
