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 · uneditedIncorrect authorization vulnerability in Cybozu Garoon 5.0.0 to 6.0.0 allows a remote authenticated attacker to alter and/or obtain the data of Memo.
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 · high confidenceCybozu Garoon versions 5.0.0 to 6.0.0 contains an incorrect authorization vulnerability in the Memo application. An authenticated remote attacker can alter and/or obtain data of Memo records that they should not have access to, likely due to missing or improper access control checks on Memo resources.

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 Cybozu Garoon installed versionAccess the system administration screen or check the product information panel in Garoon. The version is typically displayed in the system settings or about page. Alternatively, check the garoon/version file if accessible via the installation directory.Affected if The installed version is 5.5.0, 5.5.1, 5.9.0, 5.9.1, or any version >= 5.5.0 but less than 6.0.1
-
Confirm Memo application is in useLog into Garoon as an administrator and navigate to the application list or system settings to verify that the Memo application (often labeled as 'Memo' or 'Bulletin Board/Memo') is installed and enabled for the system.Affected if The Memo application is installed and enabled on the Garoon system
-
Review Memo application access control settingsIn the Garoon system administration panel, locate the Memo application settings and examine the access control or permission configurations. Check if record-level access controls are properly defined for user groups and individual users.Affected if Access controls on Memo records are not explicitly defined, use broad permissive settings, or allow users to access records outside their intended scope
-
Audit recent Memo record access logsIf logging is enabled, review the Garoon audit logs or access logs for the Memo application. Look for access events where users accessed or modified Memo records that belong to other users or groups.Affected if Logs show unauthorized access patterns or cross-user data access in the Memo module
You are affected if your Cybozu Garoon version is 5.5.0 or higher but below 6.0.1, the Memo application is enabled, and access controls on Memo records are missing or improperly configured.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped6.0.1
Apply the vendor patch or upgrade to a patched version of Cybozu Garoon as specified in the vendor's security advisory. If patches are unavailable, implement compensating controls such as strict session validation and request-level authorization checks on Memo operations.
6.0.1
- 1. Back up all Garoon data and configuration before upgrading.
- 2. Verify current Garoon version is within the affected range (5.0.0 to 6.0.0).
- 3. Obtain the Garoon 6.0.1 installer from official Cybozu distribution channels.
- 4. Follow Cybozu's standard upgrade procedure for Garoon (refer to official installation/upgrade guide).
- 5. After upgrade, verify the Memo application functions correctly.
- 6. Confirm the version has been updated to 6.0.1 or later.
