CVE-2023-42820
This vulnerability is due to exposing the random number seed to the API, potentially allowing the randomly generated verification codes to be replayed, which could lead to password resets.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
