Devise Two Factor
Monthly
Under the default configuration, Devise-Two-Factor versions >= 2.2.0 & < 6.0.0 generate TOTP shared secrets that are 120 bits instead of the 128-bit minimum defined by RFC 4226. Rated medium severity (CVSS 6.0), this vulnerability is remotely exploitable. No vendor patch available.
Tinfoil Devise-two-factor before 2.0.0 does not strictly follow section 5.2 of RFC 6238 and does not "burn" a successfully validated one-time password (aka OTP), which allows remote or physically. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable.
