nocodbnpmDescription
NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, 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 This vulnerability is fixed in 2026.05.1.

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.
Remediation status
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.
Mitigate without a patch
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 CVE-2026-53927 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 CVE-2026-53927. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
