WP OAuth Server vulnerabilities

The WP OAuth Server plugin (miniOrange) in versions up to 6.4.0 contains a missing authorization vulnerability, allowing exploitation of incorrectly configured access control security levels.

Unauthenticated SQL Injection vulnerability in WP OAuth Server versions up to 6.2.0.

The WP OAuth Server (Login with WordPress) WordPress plugin before 6.3.1 does not restrict access to the debug log it writes, which is stored at a fixed and publicly reachable location, allowing unauthenticated users to read the OAuth tokens and authorisation codes it has issued as well as user records including password hashes when debug logging is enabled.
