Application crash via XML type heap overwrite
Published Jun 17, 2026 · Updated Jun 17, 2026
Heap-based buffer overflow in affected RTI Connext Professional releases allows remote attackers to crash applications via malicious XML. The XML type parser can overwrite a heap buffer and leak memory while Core Libraries or dependent Infrastructure Services parse attacker-controlled XML. Remote reachability requires Routing Service's load administration command; otherwise malicious XML must reach an application during startup or runtime, and successful corruption can alter memory or terminate the process.

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=5.0.0 <5.2.*
- Affected versionversion=5.3.0 <5.3.*
- Affected versionversion=6.0.0 <6.0.*
- Affected versionversion=6.1.0 <6.1.*
- Affected versionversion=7.0.0 <7.3.1.3
