CVE-2026-88403Network attack vector

Authenticated internal-resource scanning via crafted serverRequest request

Published Sep 21, 2026 · Updated Sep 22, 2026

SSRF in NocoBase 2.1.21 allows remote authenticated users to scan internal resources through a crafted HTTP request. The available record identifies serverRequest as the locus but does not disclose how the function fails to restrict the crafted request or its destination. A valid application account and network access to the HTTP interface are required; the demonstrated consequence is internal-resource enumeration.
