• CVE-2023-49781: 0.61% estimated exploitation activity in the next 30 days; percentile 49.03 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary A stored cross-site scripting vulnerability exists within the Formula virtual cell comments functionality. Details The nc-gui/components/virtual-cell/Formula.vue displays a v-html tag with the value of "urls" whose contents are processed by the function replaceUrlsWithLink(). This function recognizes the pattern URI::(XXX) and creates a hyperlink tag <a with href=XXX. However, it leaves all the other contents outside of the pattern URI::(XXX) unchanged, which makes the evil users can create a malicious table with a formula field whose payload is <img src=1 onerror="malicious javascripts"URI::(XXX). The evil users then can share this table with others by enabling public viewing and the victims who open the shared link can be attacked. PoC Step 1: Attacker login the nocodb and creates a table with two fields, "T" and "F". The type of field "T" is "SingleLineText", and the type of the "F" is "Fomula" with the formula content {T} Step 2: The attacker sets the contents of T using…

# Patch Next advisory brief: CVE-2023-49781

Advisory: NocoDB Vulnerable to Stored Cross-Site Scripting in Formula.vue
IDs: CVE-2023-49781, GHSA-h6r4-xvw6-jc5h
Record: https://patchnext.com/advisories/cve-2023-49781 (revision 2, source checked 26 Oct 2026, 12:37 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: nocodb 0.202.9. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm nocodb: affected <= 0.202.8; fixed in 0.202.9

## Suggested inspection (read-only)
- `npm ls nocodb --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on nocodb.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-h6r4-xvw6-jc5h (OSV record GHSA-h6r4-xvw6-jc5h lists affected ranges: npm nocodb >=0 <0.202.9 (fixed))
