Directory information disclosure via path traversal
Published May 16, 2024 · Updated Apr 28, 2026
Path traversal in JCH Optimize 4.2.0 and earlier allows remote authenticated users to access directory information. The Optimize Image page fails to confine supplied paths to its intended directory; the publisher has not disclosed the parameter or handler. Subscriber-level access is required, and the published assessment limits the consequence to confidentiality, with no file modification or service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=- <=4.2.0
- Affected versionversion=n/a <=4.2.0 changes=[{"at":"4.2.1","status":"unaffected"}]
