CVE-2025-6710Network attack vector

Server crash via excessive JSON recursion

Published Jun 26, 2025 · Updated Jun 26, 2025

Uncontrolled recursion in MongoDB Server 7.0 before 7.0.17 and 8.0 before 8.0.5 allows remote attackers to crash the server. The JSON parser recursively processes attacker-supplied nested structures without enforcing a depth limit, exhausting stack space and terminating the server process. MongoDB Server 6.0 before 6.0.21 has the same crash condition, but remote authenticated users must reach the parser.
