WordPress · Wp Oauth Server · CVE-2026-19715
**Name of the Vulnerable Software and Affected Versions**
WP OAuth Server ( Login with WordPress ) versions prior to 6.3.1
**Description**
When debug logging is enabled, the plugin fails to restrict access to its debug log. Because the log is stored at a fixed and publicly reachable location, unauthenticated users can read sensitive information, including issued OAuth tokens, authorization codes, and user records containing password hashes.
**Recommendations**
Update to version 6.3.1 or later.
As a temporary mitigation, disable debug logging to prevent the creation of the publicly accessible log file.
