GHSA-WX8Q-RGFR-CF6V

Vulnerability from github – Published: 2021-11-10 18:20 – Updated: 2021-12-10 18:30
VLAI?
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).
