devise Time-of-check Time-of-use Race Condition vulnerability

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.

Devise Gem for Ruby Unauthorized Access Using "Remember Me" Cookie

Devise version before 3.5.4 uses cookies to implement a Remember me functionality. However, it generates the same cookie for all devices. If an attacker manages to steal a remember me cookie and the user does not change the password frequently, the cookie can be used to gain access to the application indefinitely.

Authentication Bypass in Devise

An issue was discovered in Plataformatec Devise before 4.7.1. It confirms accounts upon receiving a request with a blank confirmationtoken, if a database record has a blank value in the confirmationtoken column. (However, there is no scenario within Devise itself in which such database records would exist.)

Devise does not properly perform type conversion when performing database queries

Devise gem 2.2.x before 2.2.3, 2.1.x before 2.1.3, 2.0.x before 2.0.5, and 1.5.x before 1.5.4 for Ruby, when using certain databases, does not properly perform type conversion when performing database queries, which might allow remote attackers to cause incorrect results to be returned and bypass security checks via unknown vectors, as demonstrated by resetting passwords of arbitrary accounts.

Devise Gem for Ruby Unauthorized Access Using Remember Me Cookie

Devise version before 3.5.4 uses cookies to implement a Remember me functionality. However, it generates the same cookie for all devices. If an attacker manages to steal a remember me cookie and the user does not change the password frequently, the cookie can be used to gain access to the application indefinitely.

Devise Gem for Ruby confirmation token validation with a blank string

Devise before 4.7.1 confirms accounts upon receiving a request with a blank confirmationtoken, if a database record has a blank value in the confirmationtoken column. However, there is no scenario within Devise itself in which such database records would exist.

Devise Gem for Ruby Time-of-check Time-of-use race condition with lockable module

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.

CSRF token fixation attacks in Devise

Devise contains a flaw that allows a remote, user-assisted attacker to conduct a CSRF token fixation attack. This issue is triggered as previous CSRF tokens are not properly invalidated when a new token is created. If an attacker has knowledge of said token, a specially crafted request can be made to it, allowing the attacker to conduct CSRF attacks.
