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
Grayscale Blog 0.8.0, and possibly earlier versions, allows remote attackers to gain privileges via direct requests with modified arguments in (1) the user_permissions parameter to add_users.php, and unspecified parameters to (2) addblog.php, (3) editblog.php, (4) editlinks.php, (5) edit_users.php, and (6) add_links.php.

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 confidence

Grayscale Blog 0.8.0 contains an insecure direct object reference vulnerability allowing remote attackers to escalate privileges by manipulating the user_permissions parameter in add_users.php and unspecified parameters in multiple admin files (addblog.php, editblog.php, editlinks.php, edit_users.php, add_links.php). This enables unauthenticated or low-privilege users to gain administrative access.

MitigationImplement proper server-side authorization checks and input validation on all administrative functions, particularly around user permission assignments. If no patched version exists, restrict admin page access by IP or require stronger authentication.

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 Grayscale Blog installation
    Locate the Grayscale Blog installation directory and check for index.php or other core files that identify this application
    Affected if The application installed is Grayscale Blog and the version is 0.8.0 or lower
  2. Check installed version
    Open the main PHP files or any version file in the installation directory and compare the version number to 0.8.0
    Affected if The version is 0.8.0 or any version lower than 0.8.0
  3. Verify admin script presence
    Check for the existence of add_users.php, addblog.php, editblog.php, editlinks.php, edit_users.php, and add_links.php in an admin or administrative directory
    Affected if These admin scripts exist in the application
  4. Inspect add_users.php for vulnerable parameter
    Open add_users.php in a text editor and search for the user_permissions parameter being used without proper authorization validation
    Affected if The user_permissions parameter is processed without verifying the requester has admin privileges
  5. Test admin page access controls
    Attempt to access the admin pages directly without logging in or with a low-privilege account to see if authorization checks are enforced
    Affected if Admin pages are accessible without authentication or without proper privilege verification
  6. Review permission handling in admin scripts
    Examine the code in add_users.php and other admin files to see if user-supplied permission values are validated against the current user's permissions
    Affected if Permission values from the request are used directly without server-side validation against the session user's actual permissions

If Grayscale Blog version 0.8.0 or lower is installed and admin pages are accessible without proper authorization checks, the application is affected by this IDOR vulnerability.

Interim mitigation

Implement proper server-side authorization checks and input validation on all administrative functions, particularly around user permission assignments. If no patched version exists, restrict admin page access by IP or require stronger authentication.
