CWE-ID: CWE-672 - Operation on a Resource after Expiration or Release

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to repeatedly authenticate as an affected user.

The vulnerability exists due to operation on a resource after expiration or release in the MFA recovery code handling logic when validating recovery codes during login. A remote attacker can use an obtained recovery code multiple times to repeatedly authenticate as an affected user.

The issue affects accounts with TOTP-based multi-factor authentication enabled, and exploitation requires obtaining a valid recovery code.
