NocoDB: Reflected Cross-Site Scripting via Password Reset Token
Date: 2026-06
Affected: npm/nocodb
Attack vector: xss
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2026-47376
CWE: CWE-79

### 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: ```ejs 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. ### Credit This issue was reported by [@fg0x0](https://github.com/fg0x0).
