CVE-2026-73246

Kestra: Unauthenticated management `/worker` endpoint exposes live task configuration and plaintext credentials

State: Published
Severity: 7.5 High
Published: Aug 11, 2026
Updated: Aug 13, 2026
Reserved: Aug 11, 2026

Description

Kestra is an open-source, event-driven orchestration platform. Prior to 2.0.0-rc6, Kestra's worker/src/main/java/io/kestra/worker/endpoint/WorkerEndpoint.java serves GET /worker without authentication and serializes the complete live Task object, which can expose commands, environment variables, HTTP headers, connection details, plaintext credentials, and execution identifiers while the main API on port 8080 remains protected. This issue is fixed in 2.0.0-rc6.
