In Eclipse Ditto's Node.js JavaScript client, all released versions of @eclipse-ditto/ditto-javascript-client-node from 2.0.0 to 3.9.0 and of its predecessor package @eclipse-ditto/ditto-javascript-client-node_1.0 from 1.0.0 to 2.1.0, the WebSocket transport hard-codes rejectUnauthorized: false when creating the underlying ws WebSocket. Certificate chain and hostname validation are therefore disabled for every wss:// connection, and no builder option, constructor argument or environment variable lets an application turn validation back on. An attacker in a position to intercept the connection can present an arbitrary certificate, complete the TLS handshake, read the credentials that the configured authentication provider sends in the Authorization header of the WebSocket upgrade request, and read, alter or inject Ditto Protocol messages for the lifetime of the connection. The Java client, the browser/DOM JavaScript client and the HTTP transport of the Node.js client are not affected.

AnalysisAI
TLS certificate validation is disabled by default in the Node.js WebSocket client of Eclipse Ditto (@eclipse-ditto/ditto-javascript-client-node 2.0.0-3.9.0 and predecessor _1.0 package 1.0.0-2.1.0), which hard-codes rejectUnauthorized:false when opening every wss:// connection. A man-in-the-middle attacker can present any certificate, complete the handshake, steal the credentials sent in the WebSocket upgrade's Authorization header, and read, alter or inject Ditto Protocol messages for the connection's lifetime. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a man-in-the-middle position on the network path used by an application running the affected Node.js client (@eclipse-ditto/ditto-javascript-client-node) and using the WebSocket (wss://) transport - this is the AT:P attack requirement in the CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L) scores 9.2, but the AT:P (Attack Requirements: Present) metric is the key qualifier - exploitation requires the attacker to already occupy a man-in-the-middle position on the network path, which is a meaningful barrier compared to a purely remote flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade @eclipse-ditto/ditto-javascript-client-node to 3.9.1 (from the 3.x line) or 3.8.1 (patched maintenance release), and migrate off the end-of-line predecessor package @eclipse-ditto/ditto-javascript-client-node_1.0 (1.0.0-2.1.0) onto a fixed 3.x release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify deployments using @eclipse-ditto/ditto-javascript-client-node via package.json and npm audit; isolate affected systems from untrusted networks or require VPN tunneling if unavoidable. …
