CVE-2026-67199

Name of the Vulnerable Software and Affected Versions Perspective version 5.0.0

Description A denial of service issue exists where remote attackers can block the server event loop indefinitely. This occurs by submitting a crafted expression containing unbounded for or while loop constructs within a TableMakeViewReq message. By embedding an arbitrarily large iteration count in an expression column evaluated once per table row, the Tornado IOLoop blocks without an iteration cap, deadline, or cancellation check, making the server unresponsive to all connected clients.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
