How severe is CVE-2023-50717?

CVE-2023-50717 has a CVSS score of 5.7/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2023-50717?

CVE-2023-50717 affects the following packages: nocodb (npm). Ecosystems affected: npm.

How do I fix CVE-2023-50717?

Update nocodb to 0.202.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-50717 is resolved across your whole dependency graph.

How do I detect CVE-2023-50717 in my npm dependencies?

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.

How do I mitigate CVE-2023-50717 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2023-50717?

O3 pinpoints whether CVE-2023-50717 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2023-50717 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-50717 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2023-50717?

CVE-2023-50717 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 43th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2023-50717?

CVE-2023-50717 is classified as Cross-site Scripting (XSS) (CWE-79), Unrestricted File Upload (CWE-434). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2023-50717 published, and has it been updated?

CVE-2023-50717 was published on May 13, 2024 and was last updated on March 14, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

NocoDB is software for building databases as spreadsheets. Starting in verson 0.202.6 and prior to version 0.202.10, an attacker can upload a html file with malicious content. If user tries to open that file in browser malicious scripts can be executed leading stored cross-site scripting attack. This allows remote attacker to execute JavaScript code in the context of the user accessing the vector. An attacker could have used this vulnerability to execute requests in the name of a logged-in user or potentially collect information about the attacked user by displaying a malicious form. Version 0.202.10 contains a patch for the issue.
