Summary
NocoDB before 2026.08.0 contains a stored cross-site scripting vulnerability that allows authenticated Creator users to inject script by embedding markup in column or table titles. The Delete.vue confirmation dialog renders these titles through an unescaped innerHTML binding, executing script when a victim deletes an external-source table to steal session tokens from localStorage.
Who should check
Teams running NocoDB before 2026.08.0 where base Creator users can create link columns and external-source tables are deleted, such as base owners and administrators who confirm deletions.

What to do
Check whether your setup matches what the bug needs.
Attacker needs an authenticated session with permission to create columns (base Creator role). Victim must confirm deletion of a table on an external (non-meta) data source that still has link columns pointing at it. Affects NocoDB versions before 2026.08.0.Upgrade to a fixed version: 2026.08.0.
Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-126274 (NocoDB before 2026.08.0 Stored XSS via Table Deletion Dialog), 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.

Conditions (all must be true for the bug to be hit):
- Attacker needs an authenticated session with permission to create columns (base Creator role). (source: https://github.com/nocodb/nocodb/security/advisories/GHSA-638g-xw92-xq9x)
- Victim must confirm deletion of a table on an external (non-meta) data source that still has link columns pointing at it. (source: https://github.com/nocodb/nocodb/security/advisories/GHSA-638g-xw92-xq9x)
- Affects NocoDB versions before 2026.08.0. (source: https://www.vulncheck.com/advisories/nocodb-before-2026.08.0-stored-xss-via-table-deletion-dialog)

Attacker needs: network access, low-privilege login, a user action.
CISA KEV: CVE-2026-126274 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126274 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:
- https://github.com/nocodb/nocodb/security/advisories/GHSA-638g-xw92-xq9x
- https://www.vulncheck.com/advisories/nocodb-before-2026.08.0-stored-xss-via-table-deletion-dialog
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.
Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-126274
Is CVE-2026-126274 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: cve.now feed data
What does this mean?
A stored cross-site scripting flaw lets script saved through the table creation path run in the browser of a user who confirms deletion of a table. The script can read the session token from localStorage, act as that user through the authenticated API, and export data that user can reach.Source: github.com, vulncheck.com
Which versions are affected by CVE-2026-126274?
nocodb: before 2026.08.0.Source: cve.now feed data
Am I affected, and how do I check?
NocoDB versions before 2026.08.0 are affected. The flaw applies only to tables on an external (non-meta) data source that still have link columns pointing at them, and the attacker needs an authenticated session with the base Creator role. To check a installation's version, look at the NocoDB version shown in the instance or the release tag it was deployed from.Source: github.com, vulncheck.com
How do I fix CVE-2026-126274?
Upgrade NocoDB to 2026.08.0 or later, which is the fixed version listed for this vulnerability.Source: github.com, vulncheck.com
