Published Jun 10, 2025 · Updated Jun 10, 2025

Cross-site scripting in SolarWinds Observability Self-Hosted 2025.1.1 and earlier allows remote attackers to execute script via a crafted URL. A URL field reaches the browser DOM without sanitization, causing attacker-controlled content in that field to be interpreted as active script. An administrator-level account and user interaction are required, and execution occurs in the affected web-console session.
