MoguBlog through 6.2 fails to authenticate requests to the /web/comment/closeEmailNotification endpoint, allowing unauthenticated attackers to disable email notifications for arbitrary users. Remote callers can modify the startEmailNotification flag in Redis cache for any user identifier to suppress reply notifications without authorization.
AnalysisAI
Unauthenticated integrity manipulation in MoguBlog through 6.2 allows any remote caller to silently disable email reply notifications for arbitrary users by invoking the unprotected /web/comment/closeEmailNotification REST endpoint. The root cause is a missing authentication gate in WebSecurityConfig.java, which permits the endpoint to be reached without a session or credentials, directly writing a suppression flag into the Redis-backed user cache. …
