- Nezha Dashboard before 2.6.0 Multiple Authorization and Tenant Isolation Flaws
- Details
-
Nezha Dashboard before 2.6.0 contains multiple authorization, tenant isolation, and resource exhaustion vulnerabilities that allow members or unauthenticated attackers to abuse NAT, DDNS, OAuth, cron, and server transfer features. Attackers can claim undeclared Dashboard hostnames to capture login bodies, hijack DDNS profiles, create executable schedules without exec scope, or exhaust memory via buffered NAT requests.
