GHSA-8vm4-g489-v3w7
NocoDB Vulnerable to Stored Cross-Site Scripting via Comments and Rich Text Cells
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.
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
nocodbnpmDescription
Summary
User-controlled content in comments and rich text cells was rendered via v-html without sanitization, enabling stored XSS.
Details
Comments in Comments.vue and rich text in TextArea.vue were parsed by markdown-it with html: true and injected via v-html. The codebase had vue-dompurify-html available but these paths used raw v-html. Server-side, Comment.insert() used extractProps() instead of extractPropsAndSanitize().
Commenter role is sufficient for the comments vector; Editor role for rich text.
This issue was independently reported; see also GHSA-rcph-x7mj-54mm and GHSA-wwp2-x4rj-j8rm for the same root cause found by GitHub Security Lab.
Impact
Stored XSS — malicious scripts execute for any user viewing the comment or cell.

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 0.301.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8vm4-g489-v3w7 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-8vm4-g489-v3w7 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-8vm4-g489-v3w7. 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-8vm4-g489-v3w7 in your dependencies?
O3 detects GHSA-8vm4-g489-v3w7 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
