CPE2025-052 – Vulnerability Mitigation/Remediation for Therefore™ Online and Therefore™ On-Premises – 31 October 2025

Description:
Therefore Corporation GmbH has recently become aware that Therefore™ Online and Therefore™ On-Premises contain an account impersonation vulnerability. A malicious user may potentially be able to impersonate the web service account or the account of a service using the API when connecting to the Therefore™ Server. If the malicious user gains this impersonation user access, then it is possible for them to access the documents stored in Therefore™. This impersonation is at application level (Therefore access level), not the operating system level.

Affected Versions:
All Therefore™ Online and Therefore™ On-Premises versions.

Remediation/Mitigation:
For Therefore™ Online systems, customers have already been patched. No further action is required from users or administrators.

For Therefore™ On-Premises systems, a hotfix is available to install. We strongly recommend patching all Therefore™ On-Premises systems, regardless of version. We request our customers to please contact your local Canon office or authorized reseller partner for more information.

Please note that Therefore Corporation GmbH resolved this issue by releasing a hotfix on 20 October 2025.
