ruby-devise-two-factor: Under the default configuration, Devise-Two-Factor versions >= 2.2.0 & < 6.0.0 generate TOTP shared secrets...
CVE-2024-8796 is fixed in ruby-devise-two-factor on 1 platform, first by ruby-devise-two-factor 3.1.0-2ubuntu0.1~esm1, released September 17, 2024. It is not reported as exploited. Patch Radar priority: Routine.
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. Using a shared secret shorter than the minimum to generate a multi-factor authentication code could make it easier for an attacker to guess the shared secret and generate valid TOTP codes.
