How to Fix CVE-2026-47379

To remediate this vulnerability, upgrade all affected NocoDB dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

nocodb fixed: 2026.05.1 
npm install nocodb@2026.05.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls nocodb

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-47379, inspect your project dependencies using npm:

npm ls nocodb

Analyze the terminal output to locate any version of NocoDB in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.05.1), your application is affected.

Note: The npm ls nocodb command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-203: Observable Discrepancy, where the product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. In NocoDB, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary The shared-view password check fell back to strict-equality (`===`) comparison for legacy plaintext passwords, leaking the password's length and per-character prefix through response timing. ### Details The bcrypt branch (hashes starting with `$2a$`/`$2b$`) was unaffected. The legacy fallback in `View.ts` now uses `crypto.timingSafeEqual` and a same-length dummy compare on the length-mismatch path, so total comparison time is approximately length-independent. The EE dashboard model's `verifyPassword` is patched the same way. ### Impact A network-positioned attacker could mount a timing oracle against shared views whose passwords predated the bcrypt migration. Exploitation requires the ability to time shared-view authentication responses but no prior authentication. ### Credit This issue was reported by [@Proscan-one](https://github.com/Proscan-one).
