title: Devise Gem for Ruby Time-of-check Time-of-use race condition with lockable module | ||
date: 2019-02-07 | ||
description: | | ||
Devise ruby gem before 4.6.0 when the `lockable` module is used is vulnerable to a | ||
time-of-check time-of-use (TOCTOU) race condition due to `increment_failed_attempts` | ||
within the `Devise::Models::Lockable` class not being concurrency safe. | ||
patched_versions: | ||
- ">= 4.6.0" |
