NocoDB: Reflected Cross-Site Scripting via Password Reset Token
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

nocodbnpmDescription
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nocodb. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update nocodb to 2026.04.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6xcx-7qmg-vjfq is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-6xcx-7qmg-vjfq is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-6xcx-7qmg-vjfq. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-6xcx-7qmg-vjfq in your dependencies?
O3 detects GHSA-6xcx-7qmg-vjfq across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
