NocoDB: Plaintext Password Comparison in Shared Views
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

nocodbnpmDescription
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.

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.
Fix
Update nocodb to 2026.05.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qhxg-623c-cfjm is resolved across your whole dependency graph.
Workarounds
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 GHSA-qhxg-623c-cfjm 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 GHSA-qhxg-623c-cfjm. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-qhxg-623c-cfjm in your dependencies?
O3 detects GHSA-qhxg-623c-cfjm across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
