An authentication bypass vulnerability exists in the protection of Actuator endpoints. (CVE-2026-78214)
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.
AI Analysis
Technical Summary
CVE-2026-78214 is an authentication bypass vulnerability in Apache DolphinScheduler's Actuator endpoint protection. The application determines authentication requirements by matching request paths against protected Actuator paths. An attacker can exploit this by sending a specially crafted request containing a percent-encoded path, which causes the security check to misidentify the request as not targeting a protected endpoint. This allows the attacker to bypass authentication and access restricted Actuator endpoints, potentially exposing operational or configuration data and sensitive management functions. The vulnerability affects versions before 3.4.3, which contains the fix.
Potential Impact
Successful exploitation allows a remote unauthenticated attacker to bypass authentication controls on Actuator endpoints, potentially exposing operational or configuration information. Depending on enabled endpoints and application configuration, this may lead to unauthorized access to sensitive management functionality. The CVSS score is 5.3 (medium severity), indicating limited confidentiality impact and no integrity or availability impact.
Mitigation Recommendations
Users should upgrade Apache DolphinScheduler to version 3.4.3 or later, which contains the official fix for this vulnerability. No other mitigations are indicated by the vendor advisory.
