NocoDB: Plaintext Password Comparison in Shared Views

CVE-2026-47379

Description

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.

Vulnerability mechanics

Root cause

"The shared-view password check used a strict-equality comparison for legacy plaintext passwords, enabling timing attacks."

Attack vector

A network-positioned attacker can exploit this vulnerability by timing authentication responses for shared views that use legacy plaintext passwords. The vulnerability affects shared views whose passwords predated the bcrypt migration. Exploitation requires the ability to time these responses but does not require prior authentication. The attacker can use the timing differences to infer the password's length and characters, effectively creating a timing oracle.

Affected code

The vulnerability exists in the legacy fallback password check within `View.ts` and the EE dashboard model's `verifyPassword` function. The patch specifically addresses the comparison logic in these areas.

What the fix does

The patch modifies the password comparison logic in `View.ts` and the EE dashboard model's `verifyPassword` function. For legacy plaintext passwords, the comparison now uses `crypto.timingSafeEqual`. Additionally, a same-length dummy comparison is performed on the length-mismatch path. This ensures that the total comparison time is approximately length-independent, mitigating the timing oracle vulnerability.

Preconditions

  • inputThe shared view must be configured with a legacy plaintext password (not a bcrypt hash).
  • networkThe attacker must be able to measure the time taken for authentication responses.
