MicroRealEstate is affected by broken object-level access controls in PDF generator functionality.
This issue affects MicroRealEstate: through 1.0.0-alpha3.
AnalysisAI
Sensitive document disclosure in MicroRealEstate through 1.0.0-alpha3 lets an authenticated low-privilege user retrieve PDF documents belonging to other tenants or organizations by manipulating object identifiers passed to the PDF generator. Classified under CWE-639 (IDOR) and CVSS 4.0 7.1, the flaw exposes confidential data (VC:H) without requiring integrity or availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated MicroRealEstate account (CVSS PR:L) on an instance where the PDF generator functionality is reachable, and the attacker must supply an object identifier (document/tenant/organization key) belonging to another principal - the specific feature required is the PDF document-generation endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N) describes a network-reachable, low-complexity, low-privilege attack with no user interaction that yields high confidentiality impact and no integrity or availability impact - consistent with data theft via IDOR rather than system compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated low-privilege user of a shared MicroRealEstate instance logs in and requests a PDF document, then increments or substitutes the document/tenant identifier in the request to a value they do not own. Because the PDF generator does not verify object ownership, the server returns another tenant's lease, rent notice or receipt, disclosing personal and financial data. … |
| Remediation | No vendor-released patch identified at time of analysis - the references point only to the upstream GitHub repository (https://github.com/microrealestate/microrealestate) and the reporter advisory (https://www.themissinglink.com.au/security-advisories/cve-2026-57868), with no tagged fixed release beyond 1.0.0-alpha3. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all MicroRealEstate deployments on version 1.0.0-alpha3 or earlier; review PDF export logs from January 2026 onward for sequential or anomalous document ID requests. …
