CVE-2026-47376

CVSS v4.0

5.1

Medium

VectorAV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N

Summary

The password-reset page rendered the URL token directly into a JavaScript string literal in a server-rendered EJS template. EJS <%= %> HTML-entity-encodes a fixed set of characters but does not escape single quotes or backslashes, so a crafted token could break out of the JS string context and execute attacker-controlled script in the NocoDB origin. Triggering required only that a victim follow a malicious password-reset link.

Details

The vulnerable template embedded the token as:
token: '<%= token %>',
A token containing ';alert(document.cookie);// closes the single-quoted string and runs arbitrary JavaScript. The fix moves the token into an HTML attribute (data-token="…") and reads it from dataset.token at runtime, so EJS's HTML-entity escaping is sufficient.

Impact

  • Reflected XSS in the NocoDB origin via a phished password-reset URL.
  • No authentication required to trigger; affects any user who clicks the crafted link.
  • Same-origin script can read auth state and act on the victim's behalf.
