CVE-2026-90509Public exploitNetwork attack vectorHinoki check available

Unauthenticated API access via hard-coded fallback token

Published Sep 13, 2026 · Updated Sep 13, 2026

Authentication bypass in Dromara Orion Visor 2.5.0 through 2.5.7 allows remote attackers to access agent-facing APIs. ExposeApiAspect.beforeExposeApi trusts a public fallback token from application-prod.yaml after PermitAll exempts the endpoints from Spring Security. Exploitation requires deployments that leave API_EXPOSE_TOKEN at its shipped default; exposed endpoints can alter agent state and submit host metrics.
