Description
Impact
Users or API keys with permission to expire verification codes could have expired codes that belonged to another realm if they guessed the UUID.
Patches
v1.1.2+
Workarounds
There are no workarounds, and there are no indications this has been exploited in the wild. Verification codes can only be expired by providing their 64-bit UUID, and verification codes are already valid for a very short period of time (thus the UUID rotates frequently).
