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 a Broken Access Control vulnerability in Classified Listing plugin/component versions 5.3.9 and below. The issue allows subscriber-level users to access resources or perform actions beyond their intended privileges, likely due to missing or inadequate authorization checks on certain listing-related functionality.

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 the installed Classified Listing versionAccess the plugin/component management interface in your CMS or application, or check the version metadata in the component's manifest fileAffected if The installed version is 5.3.9 or any version lower than 5.3.9
-
Confirm subscriber-level user accounts existReview your user management system to enumerate accounts with subscriber or equivalent low-privilege rolesAffected if Subscriber accounts exist in the system and can log in
-
Test listing creation or modification accessUsing a subscriber-level test account, attempt to create, edit, or delete a listing through the Classified Listing interface or API endpointsAffected if A subscriber user can perform actions that should require higher privileges (such as publishing listings, accessing other users listings, or modifying content they do not own)
-
Inspect role permission configurationCheck the Classified Listing plugin settings or configuration files for role-based access control definitions, specifically examining what permissions are assigned to subscriber rolesAffected if Subscriber role is granted permissions beyond basic read access, such as write, delete, or publish capabilities on listings
Your environment is affected if the Classified Listing component is version 5.3.9 or below AND subscriber-level users can perform privileged actions on listings.
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 · scopedUpgrade to a version higher than 5.3.9 once available, or apply vendor-provided patch. Review user role permissions and implement proper authorization checks on all listing endpoints.
Version greater than 5.3.9 (consult WordPress plugin repository for latest patched release)
- 1. Check the WordPress admin dashboard for plugin updates for the Classified Listing plugin.
- 2. If an update is available, review the changelog to confirm it addresses authorization/broken access control issues.
- 3. Update the Classified Listing plugin to the latest available version.
- 4. After updating, verify that the subscriber role no longer has unauthorized access to classified listing administrative functions.
- 5. Test with a subscriber account to confirm the vulnerability is remediated.
