• CVE-2026-24769: 0.43% estimated exploitation activity in the next 30 days; percentile 37.67 (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 (XSS) vulnerability exists in NocoDB’s attachment handling mechanism. Authenticated users can upload malicious SVG files containing embedded JavaScript, which are later rendered inline and executed in the browsers of other users who view the attachment. Because the malicious payload is stored server-side and executed under the application’s origin, successful exploitation can lead to account compromise, data exfiltration and unauthorized actions performed on behalf of affected users. --- Vulnerability Details NocoDB allows file attachments to be previewed inline based on their MIME type. Due to overly permissive MIME type checks and a lack of content sanitization, SVG files containing executable JavaScript are incorrectly treated as safe image content and rendered directly in the browser. Root Cause The vulnerability results from a combination of overly permissive MIME type classification and unsafe file serving behavior. 1. Permissive MIME Type…

# Patch Next advisory brief: CVE-2026-24769

Advisory: NocoDB Vulnerable to Stored Cross-Site Scripting via SVG upload
IDs: CVE-2026-24769, GHSA-q5c6-h22r-qpwr
Record: https://patchnext.com/advisories/cve-2026-24769 (revision 3, source checked 26 Oct 2026, 12:41 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: nocodb 0.301.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm nocodb: affected < 0.301.0; fixed in 0.301.0

## 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
