CVE-2025-66910Public exploit

Administrator credential disclosure via plaintext authentication cache

Published Dec 19, 2025 · Updated Dec 19, 2025

Plaintext password storage in Turms Server 0.10.0-SNAPSHOT and earlier allows local users to extract administrator credentials. BaseAdminService.authenticate stores a successful login's raw password in AdminInfo.rawPassword and reuses it from in-memory maps instead of retaining only the bcrypt hash. Exploitation requires privileged local access to dump or inspect the Java heap, exposing immediately usable administrator passwords without interrupting the service.
