Summary
NocoDB before 2026.06.2 contains a stored cross-site scripting vulnerability in PromptWithFields.vue that renders unescaped field references from AI field prompts as HTML in a tooltip. Attackers with the Creator role or above can store markup in a prompt's field reference that executes when victims open the field configuration, stealing the localStorage session token to call authenticated APIs as the victim.
Who should check
Teams running NocoDB before 2026.06.2 where users with the Creator role or above configure AI fields with field references in prompts

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-2026-126279 (NocoDB before 2026.06.2 Stored XSS via AI Field Prompt Tooltip), 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.

CISA KEV: CVE-2026-126279 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126279 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-j96w-qm45-vgp2
- https://www.vulncheck.com/advisories/nocodb-before-2026.06.2-stored-xss-via-ai-field-prompt-tooltip
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.
