Severity

6.5 (Medium) CVSS_V3 - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L CVSS Calculator

Summary

Insufficient Granularity of Access Control in github.com/google/exposure-notifications-verification-server

Details

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).
