CVE-2026-47379
NocoDB: Plaintext Password Comparison in Shared Views
NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, 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. This vulnerability is fixed in 2026.05.1.

NocoDB: Plaintext Password Comparison in Shared Views
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.
