SCA: security update for dagu (GHSA-9wmw-9wph-2vwp)

high Tenable Self-Hosted Container Security Plugin ID 438766

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Dagu is a workflow engine with a built-in Web user interface. Prior to 2.2.4, when Dagu is configured with
 HTTP Basic authentication (DAGU_AUTH_MODE=basic), all Server-Sent Events (SSE) endpoints are accessible
 without any credentials. This allows unauthenticated attackers to access real-time DAG execution data,
 workflow configurations, execution logs, and queue status — bypassing the authentication that protects the
 REST API. The buildStreamAuthOptions() function builds authentication options for SSE/streaming endpoints.
 When the auth mode is basic, it returns an auth.Options struct with BasicAuthEnabled: true but
 AuthRequired defaults to false (Go zero value). The authentication middleware at
 internal/service/frontend/auth/middleware.go allows unauthenticated requests when AuthRequired is false.
 This vulnerability is fixed in 2.2.4. (CVE-2026-31882)

Solution

Update the dagu library and its related packages to version 2.2.4 or later.
