Security readout for executives and security teams
Plain-English summary
CVLand reportedly lets a logged-in user bypass authorization by controlling an object key or parameter. In practical terms, a lower-privileged user may access or alter data they should not control. The issue is rated critical because confidentiality and integrity impact are high, but the provided sources do not show confirmed active exploitation.
Executive priority
Treat this as urgent for any production CVLand deployment, especially internet-facing systems. Prioritize inventory, exposure reduction, and vendor guidance tracking because no confirmed patch information is included in the provided sources.
Technical view
CVE-2025-0987 is a CWE-639 authorization bypass in CB Project Ltd. Co. CVLand, described as IDOR and parameter injection. CVSS 3.1 is 9.9 with network attack vector, low complexity, low privileges required, no user interaction, changed scope, high confidentiality and integrity impact, and low availability impact.
Likely exposure
Organizations running CVLand versions from 2.1.0 through 20251103 are potentially exposed. Risk is highest for internet-accessible or multi-tenant deployments where ordinary authenticated users can interact with records, profiles, or other keyed resources.
Exploitation context
The CVE is not in KEV, and the provided sources do not confirm active exploitation or public exploit availability. The CVSS vector indicates exploitation would require a valid low-privileged account, not anonymous access.
Researcher notes
Evidence is limited to the CVE record and government advisory references. The vendor reportedly did not respond. Do not assume a patch exists from these sources. Focus validation on CWE-639 object-level authorization failures and user-controlled key handling.
Mitigation direction
- Inventory all CVLand deployments and identify versions from 2.1.0 through 20251103.
- Check CB Project and Turkish government advisories for vendor guidance, fixed versions, or workarounds.
- Restrict external access to CVLand where business operations permit.
- Review user roles and remove unnecessary low-privileged accounts.
- Increase monitoring for unusual cross-user record access or permission failures.
Validation and detection
- Confirm deployed CVLand versions against the affected range in the CVE description.
- Review application logs for unexpected access to other users' objects or records.
- Verify authorization checks enforce ownership server-side for keyed resources.
- Test in a non-production environment using authorized accounts only.
- Document whether compensating controls limit low-privileged user access.
