Default Credentials Vulnerability in Dify by LangGenius

CVE-2025-56157

What is CVE-2025-56157?

CVE-2025-56157 is a vulnerability identified in Dify, a product developed by LangGenius. Dify is designed to facilitate data integration and management tasks, utilizing PostgreSQL as its database backend. This particular vulnerability arises from the inclusion of default credentials—specifically, a hard-coded PostgreSQL username and password located within the docker-compose.yaml file in the source code of version 1.5.1. The existence of these default credentials considerably undermines the security posture of organizations utilizing Dify, as attackers can easily gain unauthorized access to databases if they exploit this oversight. This unauthorized access can lead to critical data exposure and manipulation, ultimately compromising the integrity and confidentiality of organizational data.

Potential impact of CVE-2025-56157

1. Unauthorized Database Access: The exploitation of the default credentials allows attackers to access sensitive data stored in the PostgreSQL database, potentially leading to data theft or manipulation. This can severely affect an organization’s operations and its ability to secure client information.

2. Increased Risk of Data Breaches: With default credentials publicly accessible, organizations using Dify are at heightened risk of data breaches, which often result in significant financial losses, reputational damage, and regulatory penalties.

3. System Compromise: An attacker gaining access through CVE-2025-56157 could potentially escalate privileges, allowing them to execute arbitrary commands or deploy malware, which could further compromise system security and lead to widespread disruption within the organization.
