Product section

Hybrid Cloud Observability

Cause

CVE-2026-49844 is an input validation vulnerability in Apache Log4j API that can produce malformed JSON logs when a MapMessage contains attacker-controlled NaN, Infinity, or -Infinity values. The issue is exploitable only if the application uses JsonTemplateLayout (or another layout relying on MapMessage.asJson()) and logs an attacker-controlled MapMessage. Successful exploitation can disrupt log ingestion and parsing but does not lead to remote code execution.

Resolution

Although SolarWinds Observability Self-Hosted includes a version of Log4j affected by this vulnerability, the product is not impacted because it does not use JsonTemplateLayout or the vulnerable code path.

SolarWinds Database Performance Analyzer is unaffected by this vulnerability because it does not use JsonTemplateLayout & MapMessage.asJson(), the vulnerable components.
