CVE-2026-109174 · Severity: medium · CVSS 6.5 · Published 2026-10-12

MoguBlog is a blogging platform that manages cloud storage and email configurations. The /oauth/getSystemConfig endpoint fails to restrict access properly, allowing any logged-in user to retrieve sensitive system credentials including cloud storage keys and SMTP mailbox passwords. An attacker can register a free account and immediately extract these secrets to compromise external services or intercept emails.

## Technical details

The getSystemConfig REST endpoint performs only a token validity check against the Redis user token keyspace but does not verify admin privileges or filter sensitive fields before returning the entire SystemConfig entity. An attacker with any valid end-user session token (obtainable via self-registration) can retrieve Qiniu/MinIO access and secret keys, SMTP server addresses, and email account credentials. The vulnerability is a classic broken access control issue combined with mass assignment, exposing third-party service credentials with no privilege escalation required.
