CVE-2021-22565
Insufficient Granularity of Access Control in github.com/google/exposure-notifications-verification-server
Impact
### 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). ### For more information Contact exposure-notifications-feedback@google.com
