# CVE-2026-126280: NocoDB refresh token reuse in non-atomic rotation

Affects NocoDB versions before 2026.08.0, where refresh-token rotation is not atomic, so a captured refresh token can yield a valid session. Fixed in 2026.08.0.

- Also known as: EUVD-2026-125241
- Severity: CVSS 9.1 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N
- Known exploited (CISA KEV): no
- Exposure: Unclear
- Attention: Reference. No open trigger. (last checked 2026-11-13)
- Fixed in: 2026.08.0
- Published: 2026-11-13 · Updated: 2026-11-13

CVE-2026-126280 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 9.1 (critical) and affects nocodb; fixed in 2026.08.0.

## Who should check

Teams running self-hosted or cloud NocoDB instances older than 2026.08.0 that use refresh-token sessions

Source: https://www.vulncheck.com/advisories/nocodb-before-2026.08.0-refresh-token-reuse-via-non-atomic-rotation ("NocoDB before 2026.08.0 contains a race condition")

## Affected

- nocodb: fixed in 2026.08.0

## Description

NocoDB before 2026.08.0 contains a race condition in refresh-token rotation that allows attackers to reuse tokens because UserRefreshToken.ts never checks the affected-row count. Attackers holding a captured refresh token can present it concurrently with the legitimate user to obtain a valid authenticated session, and no reuse event is recorded.

## What to do

- Check your stack: if you ship or depend on nocodb, upgrade to a fixed version (2026.08.0) per the references below.
- For agents: to check a whole dependency tree, run the stack.check operation (execute) on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-126280 (NocoDB before 2026.08.0 Refresh Token Reuse via Non-Atomic Rotation), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-126280 (entry last updated 2026-11-13):
Affected:
- nocodb nocodb: fixed in 2026.08.0
Fixed versions: 2026.08.0.
Conditions (all must be true for the bug to be hit):
- NocoDB versions before 2026.08.0 (source: https://www.vulncheck.com/advisories/nocodb-before-2026.08.0-refresh-token-reuse-via-non-atomic-rotation)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, no login, no user action.
CISA KEV: CVE-2026-126280 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126280 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:

Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

## FAQ

### Is CVE-2026-126280 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-126280

### What does this mean?

NocoDB's refresh-token rotation has a race condition, so a captured refresh token can be used to obtain a valid authenticated session as the victim user. No reuse event is recorded when this happens.
