CVE-2024-8796 not yet assigned priority: Debian including 1 source packages (ruby-devise-two-factor), 2 status rows across 2 suites (bookworm, bullseye): open 2.
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.
