Vulnerabilities
The vulnerabilities, tracked as CVE-2026-28324 and CVE-2026-28325, can be exploited without authentication.
SolarWinds has released patches for two severe vulnerabilities in Observability Self-Hosted that could be exploited for remote code execution (RCE).
Observability Self-Hosted is an on-premises and hybrid IT monitoring solution that provides organizations with unified monitoring across environments, configuration management, and control over operational data and security compliance.
The first flaw, tracked as CVE-2026-28324 (CVSS score of 9.8), is an insufficient integrity check issue leading to RCE on deployments that run non-default and non-secure configurations.
Tracked as CVE-2026-28325 (CVSS score of 8.8), the second bug is described as a deserialization of untrusted data weakness affecting installations configured to use a specific communication mode.

The vulnerabilities impact all Observability Self-Hosted versions up to 2026.2.2 and were addressed in version 2026.2.3. SolarWinds credited Kai Huang from...
