CVE-2026-47382 nocodb CVE debrief

CVE-2026-47382 is a vulnerability in NocoDB, a software for building databases as spreadsheets. The connection-test endpoint in NocoDB prior to version 2026.05.1 opened a raw TCP socket to the user-supplied database host without proper resolution and range checking. This allowed private and link-local addresses, including IPv4-mapped IPv6 forms and localhost, to be reached by the driver. The vulnerability has been fixed in version 2026.05.1. This issue has a CVSS score of 5.3 and a MEDIUM severity rating. The CVE was published on 2026-06-23T21:17:00.077Z and modified on 2026-06-25T14:21:00.260Z.

Who should care

Organizations using NocoDB prior to version 2026.05.1 should be aware of this vulnerability and take steps to mitigate it. Specifically, defenders of applications built with NocoDB should review their configurations and ensure that the connection-test endpoint is properly secured. Additionally, users of NocoDB should upgrade to version 2026.05.1 or later to prevent exploitation.

Technical summary

The connection-test endpoint in NocoDB's prior versions allowed a user-supplied database host to be connected to without proper validation. This could lead to unauthorized access to private and link-local addresses. The vulnerability is due to the lack of resolution and range checking on the destination host. The issue has been addressed in version 2026.05.1. The CVSS vector for this vulnerability is CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X.

Defensive priority

Defenders should prioritize upgrading NocoDB to version 2026.05.1 or later. Additionally, defenders should review their configurations and ensure that the connection-test endpoint is properly secured to prevent exploitation.

Recommended defensive actions

  • Upgrade NocoDB to version 2026.05.1 or later
  • Review and secure the connection-test endpoint configuration
  • Monitor for potential exploitation attempts
  • Implement compensating controls to limit access to private and link-local addresses
  • Perform regular vulnerability assessments and penetration testing
