Summary

NocoDB: Stored Cross-Site Scripting via Form View Redirect URL

Details

Summary

The shared form-view submit handler in NocoDB writes the form's redirect_url to window.location.href after a same-host check that does not validate the URL scheme. A user with editor role (or above) on any base can plant a javascript: URL in the form's redirect_url; when an authenticated viewer opens the share-link and submits the form, the payload executes in the NocoDB origin and can read the session token from localStorage["nocodb-gui-v2"].

Details

The vulnerable sink is in packages/nc-gui/composables/useSharedFormViewStore.ts:

isValidRedirectUrl validated only typeof === 'string' and non-empty trim — no scheme check.
The submit branch built an anchor element, compared anchor.host to window.location.host, and either pushState-reloaded (same host) or assigned window.location.href = redirectUrl (otherwise).
For non-network schemes such as javascript:, data:, vbscript:, and file:, anchor.host is the empty string, so the same-host check is false and the code falls into the external-redirect branch — executing the URL same-origin in the NocoDB tab.

The redirect_url field is writable by any user with editor role on the base via the form-view PATCH endpoint, and the value is returned verbatim by the public shared-view meta endpoint, so no further privilege is required to weaponize a public form share.

Impact

Same-origin script execution in the viewer's NocoDB tab. The payload runs in the NocoDB origin and can read the session token at localStorage["nocodb-gui-v2"].token.
Action under the viewer's identity. With the token, an attacker can call authenticated APIs as the viewer, scoped to whatever workspaces, bases, and operations that viewer is permitted to use.
Single-click viewer flow. Form share-links are the intended distribution channel for forms, so the phishing surface is on-brand; the form can be configured with a single hidden pre-filled required field to reduce the viewer flow to one click.

CVE-2026-47387 (GCVE-0-2026-47387)

Vulnerability from cvelistv5 – Published: 2026-06-23 20:11 – Updated: 2026-06-24 13:51

Title

NocoDB: Stored Cross-Site Scripting via Form View Redirect URL

Summary

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the shared form-view submit handler (packages/nc-gui/composables/useSharedFormViewStore.ts) in NocoDB writes the form's redirect_url to window.location.href after a same-host check that does not validate the URL scheme. A user with editor role (or above) on any base can plant a javascript: URL in the form's redirect_url; when an authenticated viewer opens the share-link and submits the form, the payload executes in the NocoDB origin and can read the session token from localStorage["nocodb-gui-v2"]. This vulnerability is fixed in 2026.05.1.

Severity

8.4 (High)
