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.
