CVE-2026-46473 May 21, 18:53 HIGH PATCH This Week

Weak secret generation in the Authen::TOTP Perl module before version 0.1.1 lets attackers predict TOTP shared secrets because they were built with Perl's non-cryptographic rand() function. Any application relying on this module to seed two-factor authentication produces guessable secrets, undermining the OTP protection it was meant to provide. There is no public exploit identified at time of analysis, and EPSS rates near-zero (0.01%) exploitation probability, but the fix (0.1.1) is confirmed in the vendor changelog.
