No CVSS score has been assigned to CVE-2026-53927 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-53927?

CVE-2026-53927 affects the following packages: nocodb (npm). Ecosystems affected: npm.

How do I fix CVE-2026-53927?

No patched version of nocodb has shipped for CVE-2026-53927 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

How do I detect CVE-2026-53927 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nocodb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-53927 if there is no patch (or I can't update yet)?

Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.

Is CVE-2026-53927 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-53927 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-2026-53927?

CVE-2026-53927 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 32th 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-2026-53927?

CVE-2026-53927 is classified as Server-Side Request Forgery (SSRF) (CWE-918). This weakness type 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-2026-53927 published, and has it been updated?

CVE-2026-53927 was published on June 23, 2026 and was last updated on October 21, 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

Summary

The spreadsheet-fetch endpoint (axiosRequestMake) accepted URLs whose path contained a permitted extension anywhere in the string, and applied a hand-rolled regex blocklist that omitted 127.0.0.0/8 and 169.254.0.0/16, allowing the cloud-metadata endpoint to be reached with a crafted URL.

Details

The extension matcher is now anchored to the end of the path or immediately before the query string (/\.(xls|xlsx|xlsm|ods|ots)(\?|$)/i and /\.(csv)(\?|$)/i), so http://169.254.169.254/credentials/.xlsx no longer satisfies the format gate. The hand-rolled IP blocklist is removed in favour of useAgent(url) from request-filtering-agent, which blocks private and loopback ranges at the socket layer.

Impact

Authenticated users with editor permission could read cloud metadata and other internal HTTP endpoints reachable from the NocoDB process. On affected installs the spreadsheet import path was a credential-exfiltration primitive on cloud hosts.
