CVE-2026-53931 nocodb CVE debrief

CVE-2026-53931 is a vulnerability in NocoDB, a software for building databases as spreadsheets. The spreadsheet-import endpoint, axiosRequestMake, could be used as a generic HTTP proxy before version 2026.05.1. This endpoint was reachable unauthenticated and had a URL-extension allowlist that was a regex tested against the full URL string. This allowed URLs whose query string ended in .csv to bypass the gate even if the underlying request was for another file. The vulnerability is fixed in version 2026.05.1. Users should update to this version to prevent potential unauthorized access. Additionally, defenders should monitor for suspicious activity and implement compensating controls to mitigate potential risks.

Who should care

Users of NocoDB, especially those who have not updated to version 2026.05.1, should be aware of this vulnerability. IT teams and security professionals responsible for maintaining and securing database systems should prioritize updating NocoDB to the latest version. Monitoring for suspicious activity and implementing compensating controls can help mitigate potential risks.

Technical summary

The vulnerability in NocoDB's spreadsheet-import endpoint allows an attacker to use it as a generic HTTP proxy. This is possible because the endpoint is reachable unauthenticated and the URL-extension allowlist is a regex tested against the full URL string. An attacker can bypass the allowlist by appending .csv to the query string of a URL, even if the underlying request is for another file. The fix in version 2026.05.1 addresses this issue by properly securing the endpoint. Technical teams should ensure that NocoDB is updated to this version to prevent exploitation.

Defensive priority

High priority should be given to updating NocoDB to version 2026.05.1. In the meantime, defenders should monitor for suspicious activity and implement compensating controls to mitigate potential risks.

Recommended defensive actions

  • Update NocoDB to version 2026.05.1 or later.
  • Monitor for suspicious activity on the network.
  • Implement compensating controls to mitigate potential risks.
  • Review and update security policies and procedures.
  • Perform vulnerability scanning and penetration testing.
