How severe is CVE-2026-47378?

No CVSS score has been assigned to CVE-2026-47378 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-47378?

CVE-2026-47378 affects the following packages: nocodb (npm). Ecosystems affected: npm.

How do I fix CVE-2026-47378?

Update nocodb to 2026.04.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-47378 is resolved across your whole dependency graph.

How do I detect CVE-2026-47378 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-2026-47378 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.

Is CVE-2026-47378 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-47378 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-2026-47378?

CVE-2026-47378 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 33th 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-2026-47378?

CVE-2026-47378 is classified as CWE-639 (CWE-639). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-47378 published, and has it been updated?

CVE-2026-47378 was published on June 23, 2026 and was last updated on August 12, 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

Public shared-view endpoints exposed values from columns that the view owner had hidden, via three independent paths: groupBy returned raw values for any column named in the request, filter and sort arrays operated on hidden columns enabling boolean-blind extraction, and the related-data list accepted arbitrary link-column IDs from other tables in the same base.

Details

A new sanitizeListArgsForPublicView helper now strips request keys that should never be caller-controlled (e.g. getHiddenColumn, nested), parses where clauses against a restricted alias map that only contains visible columns, and recursively removes filter/sort entries whose fk_column_id is not in the visible set. validateGroupByColumnNames and validateGroupColumnId reject groupBy requests whose column_name (CSV-style) or groupColumnId is not in the visible or group-by column set. relDataList now checks column.fk_model_id === currentModel.id before resolving the linked table, matching the pre-existing check on publicMmList and publicHmList.

Impact

Anyone with a shared-view UUID could enumerate hidden-column values directly (via groupBy), confirm hidden-column values by observing row counts (via filter), or read records from unrelated tables in the same base (via the related-data list). No authentication was required.
