{"cve":"CVE-2026-102281","nvd":{"published":"2026-09-28T22:17:32.050","modified":"2026-09-30T19:56:45.443","status":"Awaiting Analysis","description":"Nest is a framework for building scalable Node.js server-side applications. Prior to 11.2.4 and 12.0.2, a single message with a deeply nested object in its pattern can terminate a NestJS microservice using the TCP or RabbitMQ transport. ServerTCP#handleMessage and ServerRMQ#handleMessage pass a client-controlled non-string pattern to JSON.stringify to derive the handler lookup key; sufficiently deep nesting throws RangeError: Maximum call stack size exceeded, and the unhandled promise rejection terminates Node.js under its default behavior. An attacker who can reach the TCP port or publish to the consumed RabbitMQ queue or exchange can crash the service on demand; other transports are not affected because their patterns arrive as strings. This issue is fixed in versions 11.2.4 and 12.0.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-248","CWE-674"],"references":["https://github.com/nestjs/nest/commit/aa97b5144d8dff1ce700aac521eb86449a679d6f","https://github.com/nestjs/nest/commit/e9dcd4c7ac64361fbfe79461da85f5b3fc3e02da","https://github.com/nestjs/nest/pull/17737","https://github.com/nestjs/nest/releases/tag/v11.2.4","https://github.com/nestjs/nest/releases/tag/v12.0.2"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-102281","score":0.00586,"percentile":0.47723,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-m8vh-jmq9-5rjg","url":"https://osv.dev/vulnerability/GHSA-m8vh-jmq9-5rjg","summary":"Nest: Remote process termination via a deeply nested microservice message pattern","modified":"2026-09-30T00:00:03.849760028Z","packages":[{"ecosystem":"npm","name":"@nestjs/microservices","purl":"pkg:npm/%40nestjs/microservices","ranges":["<11.2.4"],"fixed":["11.2.4"]},{"ecosystem":"npm","name":"@nestjs/microservices","purl":"pkg:npm/%40nestjs/microservices","ranges":[">=12.0.0 <12.0.2"],"fixed":["12.0.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
