CVE-2025-64312
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPermission control vulnerability in the file management module. Impact: Successful exploitation of this vulnerability may affect service confidentiality.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an authorization vulnerability in a file management component where permission controls are insufficiently enforced. An attacker could potentially access or manipulate files beyond their authorized scope, compromising service confidentiality.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify HarmonyOS versionCheck the device or system settings for the HarmonyOS version number. On most HarmonyOS devices, this is found under Settings > About Phone > Version, or by querying the system properties via command line if available.Affected if The installed version is exactly 5.0.1, 5.1.0, or 6.0.0, matching one of the listed affected versions.
-
Locate file management componentIdentify if the native file management application or file management APIs are present and accessible on the system. This may include default file browsers, file picker components, or file access services bundled with HarmonyOS.Affected if The file management component is present and operational on the device.
-
Verify file access permission controlsInspect the file management component's permission configuration. Check if proper authorization checks are enforced on file operations such as read, write, delete, or share operations.Affected if Authorization controls are missing, weak, or can be bypassed for file operations outside the user's authorized scope.
-
Test file operation boundariesIf you have access to the system, attempt file operations across different user contexts or directories to verify whether the permission model properly restricts access beyond authorized directories.Affected if Files or directories outside the user's authorized scope can be accessed, modified, or listed through the file management component.
A device is affected if it runs HarmonyOS version 5.0.1, 5.1.0, or 6.0.0 and utilizes the vulnerable file management component with insufficient authorization controls.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement robust authorization checks at every file operation entry point and enforce principle of least privilege for file access permissions.
