CVE-2026-109174
HIGH 7.1MoguBlog through 6.2 contains an information disclosure vulnerability that allows low-privileged front-end users to read system credentials via the getSystemConfig endpoint. Attackers can supply an ordinary reader session token to retrieve unfiltered SystemConfig data, exposing Qiniu and MinIO secret keys and SMTP mailbox passwords.
Severe if exploited (CVSS 7.1), but no known exploitation and low modeled probability. Patch on a normal cadence.
