CVE-2021-29442 is an authentication bypass vulnerability affecting Alibaba Nacos versions prior to 1.4.1. It allows unauthenticated attackers to access sensitive management endpoints, specifically the /derby endpoint, when Nacos is configured to use its embedded Derby database. This vulnerability has a CVSS score of 7.5 (High), indicating a critical risk due to its network-based attack vector, low attack complexity, and high potential for confidentiality impact, as attackers can query or wipe out the database. While not listed on the KEV catalog or Hot List, and with no reported active exploitation, public exploit code exists via Nuclei templates, though community discussion and media coverage are minimal.
