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 · unedited

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 · low confidence

OpenHarmony v5.0.3 and prior versions contain a permission handling flaw that allows a local attacker to bypass intended access controls when querying permission states, resulting in unauthorized information disclosure.

MitigationApply available OpenHarmony security patches or update to a version beyond v5.0.3 that addresses the permission check vulnerability.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify OpenHarmony version
    Check system settings or run 'getprop ro.build.version.harmonyos' or 'hiupdmanager --version' to retrieve the installed OpenHarmony version
    Affected if Version is 5.0.3 or lower (any version <= 5.0.3)
  2. Verify permission query APIs are exposed
    Inspect the application's permission manager module or API endpoint configuration to determine if the permission state query interface is accessible to local applications
    Affected if Permission query APIs are exposed without proper authorization checks
  3. Check for the permission bypass condition
    Review audit logs or security event logs for unexpected permission state queries from untrusted processes or applications
    Affected if Untrusted local processes can successfully query permission states that should require elevated privileges
  4. Confirm vulnerability in permission manager
    Examine the permission manager service configuration (typically found in /system/etc/ or through the security subsystem) for the specific flaw where query requests bypass the intended authorization check
    Affected if The permission manager allows query operations without enforcing proper access control validation

A user is affected if their OpenHarmony installation is version 5.0.3 or prior AND the permission query functionality is accessible to local attackers, allowing unauthorized access to permission state information.

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.

Upgrade available Upgrade to a release after 5.0.3
Interim mitigation

Apply available OpenHarmony security patches or update to a version beyond v5.0.3 that addresses the permission check vulnerability.

Recommended fix Low confidence

OpenHarmony version > 5.0.3 (e.g., 5.0.4 or later stable release)

  1. Upgrade OpenHarmony to a version newer than 5.0.3 to remediate the permission-related information leak vulnerability
  2. Verify the upgrade does not introduce regressions in permission-related functionality
