CVE-2026-67198

perspective-dev perspectiveVulnerabilityCVSS 8.7

Perspective 5.0.0 contains a denial-of-service vulnerability in the VirtualServer protocol dispatcher that allows unauthenticated remote attackers to crash the server process by sending malformed or incomplete protobuf messages. Attackers can send well-formed requests such as ViewToArrowReq with no viewport set or MakeTableReq with no data field to trigger unwrap() calls on None values at nine distinct sites, causing the process to abort with SIGABRT.

No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.

Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution

Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.

No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
