novel-plus through 5.3.3 contains an insecure default cache-management password in the CacheController.refreshCache endpoint that allows anonymous attackers to invalidate portal caches by supplying the hardcoded default value in the URL path. Attackers can trigger unauthorized cache invalidation by accessing the cache/refresh endpoint with the known default password, forcing unnecessary database queries to repopulate the cache.
