# NocoDB: crafted link runs script and steals session tokens

Link for people: https://infrastack.ai/live/CVE-2026-126286 (this .md is for agents)

NocoDB before 2026.08.0 has a reflected cross-site scripting flaw in its page-leaving warning component, where a control character in the redirect URL scheme bypasses the scheme check. An attacker who gets a user to open a crafted link can run script in the browser and read the session token from localStorage to take over the account.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:NocoDB affected range not listed fixed no fixed version listed
- npm:nocodb affected range not listed fixed no fixed version listed

## How to check

- Check the NocoDB version in use; versions before `2026.08.0` are affected.

## Fix

- Upgrade NocoDB to `2026.08.0` or later.

## Timeline

## Documents

- [advisory] Vendor advisory: github.com https://github.com/nocodb/nocodb/security/advisories/GHSA-x3wx-294c-4p48

## From the sources

NocoDB before 2026.08.0 contains a reflected cross-site scripting vulnerability in PageLeavingWarning.vue that allows unauthenticated attackers to execute script by embedding an ASCII control character in the ncRedirectUrl scheme. Attackers can send a crafted link that bypasses the scheme check and reaches the anchor href or window.location, stealing the session token from localStorage for account takeover.
