CVE-2026-78214Apache DolphinScheduler: Actuator Endpoint Authentication Bypass via Percent-Encoded Paths
Medium 5.3
In plain English
A medium-severity incorrect authorization in Apache DolphinScheduler from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 29% of all known vulnerabilities).
Official description
An authentication bypass vulnerability exists in the protection of Actuator endpoints. The application determines whether authentication is required by matching the incoming request path against protected Actuator paths. By sending a specially crafted request containing a percent-encoded path, a remote unauthenticated attacker can cause the security check to fail to recognize the request as targeting a protected endpoint. As a result, the attacker may bypass authentication and access otherwise restricted Actuator endpoints. Successful exploitation may expose operational or configuration information and, depending on the enabled endpoints and application configuration, allow access to sensitive management functionality. This issue affects Apache DolphinScheduler: before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.
