CVE-2026-28324 is a critical unauthenticated remote code execution vulnerability in SolarWinds Observability Self-Hosted. The flaw results from insufficient verification of data authenticity (CWE-345) in deployments configured with a non-default, non-secure configuration. A remote attacker can send a malformed network request that bypasses the inadequate integrity validation and causes arbitrary code execution on the affected server. SolarWinds Observability Self-Hosted versions 2026.2.2 and earlier are affected; version 2026.2.3 remediates the vulnerability.
