What is CVE-2019-19687?
CVE-2019-19687 is a high-severity missing authorization vulnerability in n/a, published on 9 Dec 2019. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
OpenStack Keystone 15.0.0 and 16.0.0 is affected by Data Leakage in the list credentials API. Any user with a role on a project is able to list any credentials with the /v3/credentials API when enforce_scope is false. Users with a role on a project are able to view any other users' credentials, which could (for example) leak sign-on information for Time-based One Time Passwords (TOTP). Deployments with enforce_scope set to false are affected. (There will be a slight performance impact for the list credentials API once this issue is fixed.)
Weakness: CWE-522
