CVE-2026-27410Network attack vector

Unauthenticated data compromise and service interruption

Published Jun 17, 2026 · Updated Jun 17, 2026

Deserialization of untrusted data in VeronaLabs SlimStat Analytics before 5.4.0 allows remote attackers to read or alter data or interrupt service. Patchstack and the public CVE record do not identify the affected endpoint, data source, deserialization call, or object-handling path. No authentication or user interaction is required, but exploitation has high complexity and each assessed impact is limited.
