Low risk
0.23%

14th percentile - higher than 14% of all known CVEs

Summary

The OAuth Single Sign On WordPress plugin before 7.0.1 does not verify the identity assertion returned by its Steam single sign-on flow, allowing unauthenticated attackers to log in as an arbitrary non-administrator user, and to create new accounts.

Risk Assessment

The risk is severe because an attacker can gain access to user accounts without authorization, potentially leading to data breaches or further attacks.

Recommendation

Immediately update the plugin to version 7.0.1 or later. Also monitor login logs for unauthorized activity.
