Technical impact

The vulnerability in NocoDB involves a race condition in the users.service.ts file of the Registration component that can be triggered from a remote location. The CVE states that the attack requires a high level of complexity and is assessed as difficult. The description indicates that the flaw may disrupt normal registration processing or allow concurrent requests to interfere with each other, but it does not provide evidence of unauthorized actions or denial of service.

Affected Systems

All NocoDB installations built up to and including the 2026.08.0 release are affected. The description explicitly limits the impact to releases up to that point; newer versions have not been confirmed as affected.

Risk and Exploitability

The CVSS score of 6.3 classifies the risk as moderate. No EPSS score is available and the vulnerability is not listed in the CISA KEV catalog, indicating no widespread exploitation has been observed.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Identify whether the installed NocoDB version is 2026.08.0 or older and plan to move to a newer release once the vendor publishes a fix.
  • Until a patch is available, restrict external access to the registration endpoint or require prior authentication so that concurrent registration requests from untrusted sources are mitigated.
  • If possible, modify or add synchronization mechanisms to the registration service to prevent race conditions, or temporarily disable concurrent registration processing until a formal patch is released.
