AI-suggested
Organizations should immediately audit their nocobase deployments to identify affected versions. Implement strict access controls on API endpoints to limit exposure. Monitor JWT token usage for anomalies, such as unexpected token issuances or invalid signatures. Employ network-level protections like Web Application Firewalls (WAFs) to detect and block suspicious requests targeting the JWT service. Consider isolating or segmenting systems running nocobase to reduce lateral movement risk. Stay alert for vendor updates or community patches and plan for timely upgrades once available. Finally, conduct security awareness training for developers and administrators emphasizing secure key management practices to prevent similar issues.
Description
CVE-2025-13877 is a medium severity vulnerability in nocobase versions up to 1.9.4 and 2.0.0-alpha.37 involving the use of a hard-coded cryptographic key in the JWT Service component. This flaw allows remote attackers to potentially manipulate the API_KEY argument, compromising the cryptographic integrity of JWT tokens. Exploitation is difficult due to high attack complexity and no user interaction or privileges are required. The vulnerability impacts confidentiality, integrity, and availability at a low level and has a CVSS 4.0 score of 6.
