CVE-2025-67652

Credential disclosure via weak project-file encoding

Published Jan 22, 2026 · Updated Jan 22, 2026

Weak credential encoding in AutomationDirect CLICK PLC C0-0x, C0-1x, and C2-x allows local users to recover passwords from project files. Project files retain credentials with encoding that fails to protect their confidentiality, but CISA has not published the algorithm or file-field details. Access to a project file is required; recovered credentials enable impersonation, privilege escalation, and unauthorized access to associated systems and services.
