Summary

NocoDB before 2026.06.1 contains a CSV formula injection vulnerability in export.service.ts that writes record values and column titles beginning with formula characters into CSV exports without neutralization. Low-privileged collaborators, or unauthenticated users submitting a public form, can plant formulas that execute when a user opens the export in a spreadsheet application, potentially exfiltrating cell contents or invoking external commands.

Inferred packages

No advisory lists a package for this vulnerability yet. The CVE names these as products and links their GitHub repository, and the package registry names the same repository, so they are probably the affected packages. Low confidence: the versions are the CVE’s own for the product, and a stack check reports the package as unchecked when there are none.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of nocodb/nocodb published their own advisory on GitHub. Reviewed sources take precedence over it.
