CVE-2026-67198

Name of the Vulnerable Software and Affected Versions Perspective version 5.0.0

Description A denial-of-service issue exists in the VirtualServer protocol dispatcher. Unauthenticated remote attackers can crash the server process by sending malformed or incomplete protobuf messages (a language-neutral, platform-neutral, extensible mechanism for serializing structured data). Specifically, sending requests such as ViewToArrowReq without a viewport or MakeTableReq without a data field triggers unwrap() calls on None values at nine different locations, resulting in a process abort via SIGABRT.

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