Service interruption via WebSocket request buffer copy
Published Jun 17, 2026 · Updated Jun 17, 2026
Buffer overflow in RTI Connext Professional Web Integration Service allows remote attackers to interrupt service via a malicious WebSocket request. Its WebSocket request parser copies attacker-controlled data without a sufficient bounds check, permitting an out-of-bounds copy. Network access is sufficient on unsecured ports; secure ports block untrusted connections, and a successful request interrupts the service with limited data exposure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=6.1.2 <6.1.*
- Affected versionversion=7.0.0 <7.3.1.3
- Affected versionversion=7.4.0 <7.*
