CVE-2025-26394

Authenticated request redirection via unsanitized URL string

Published Jun 10, 2025 · Updated Jun 10, 2025

Open redirection in SolarWinds Observability Self-Hosted 2025.1.1 and earlier allows remote authenticated users to redirect requests via crafted URLs. SolarWinds states only that the product fails to sanitize a URL string; no affected endpoint, parameter, or sanitization path is public. Exploitation requires adjacent-network access and high-complexity manipulation, with impact limited to redirection toward an attacker-chosen site.
