CVE-2025-65784 Overview
CVE-2025-65784 is an Insecure Permissions vulnerability affecting Hubert Imoveis e Administracao Ltda Hub v2.0 version 1.27.3. This vulnerability allows authenticated attackers with low-level privileges to access other users' information via a crafted API request, representing a significant horizontal privilege escalation risk.
Critical Impact
Authenticated attackers can bypass authorization controls to access sensitive information belonging to other users through manipulated API requests, potentially exposing personal data and compromising user privacy.

Technical Details for CVE-2025-65784
Vulnerability Analysis
This vulnerability stems from improper access control implementation within the Hub v2.0 application's API endpoints. The application fails to properly validate whether an authenticated user has authorization to access resources belonging to other users. When processing API requests, the application appears to rely solely on authentication status rather than implementing proper authorization checks to verify that the requesting user has legitimate access to the requested data.
This type of Insecure Direct Object Reference (IDOR) vulnerability allows any authenticated user, regardless of their privilege level, to manipulate API request parameters to retrieve information belonging to other users. The impact includes potential exposure of personal information, account details, and other sensitive data managed within the real estate and property management platform.
Root Cause
The root cause of CVE-2025-65784 is insufficient authorization validation in the API request handling logic. The application authenticates users but fails to implement proper access control checks that verify whether the authenticated user is authorized to access the specific resources they are requesting. This represents a broken access control vulnerability where user identity verification exists, but resource-level authorization is missing or improperly implemented.
Attack Vector
An attacker must first obtain valid credentials with low-level privileges to authenticate to the Hub v2.0 application. Once authenticated, the attacker can craft malicious API requests by manipulating resource identifiers or parameters to reference data belonging to other users. The application processes these requests without validating the relationship between the authenticated user and the requested resources, thereby disclosing unauthorized information.
The vulnerability requires network access to the application's API endpoints and valid authentication credentials. Attackers can systematically enumerate and extract other users' data by iterating through identifiable resource parameters in their crafted API requests.
Detection Methods for CVE-2025-65784
Indicators of Compromise
- Unusual API request patterns from authenticated users attempting to access resources outside their normal scope
- Increased volume of API calls to user information endpoints from single accounts
- Sequential or systematic enumeration of user identifiers in API request logs
- Access log entries showing users retrieving information for accounts they do not own
Detection Strategies
- Implement API request monitoring to identify access patterns indicative of IDOR exploitation attempts
- Deploy anomaly detection rules to flag users accessing unusually high numbers of different user records
- Configure web application firewall (WAF) rules to detect parameter manipulation in API requests
- Enable detailed logging of all API requests including user identity and requested resource identifiers
Monitoring Recommendations
- Monitor API endpoint access logs for patterns of unauthorized data access attempts
- Set up alerts for authenticated users accessing resources belonging to multiple different user accounts
- Review access control logs periodically to identify potential exploitation of this vulnerability
- Implement rate limiting on user information API endpoints to slow down enumeration attacks
How to Mitigate CVE-2025-65784
Immediate Actions Required
- Restrict access to affected API endpoints until proper authorization controls can be implemented
- Audit existing API access logs to identify potential past exploitation of this vulnerability
- Implement additional server-side authorization checks to validate user permissions for each resource request
- Review and strengthen access control policies across all API endpoints handling user data
Patch Information
No vendor patch information is currently available for this vulnerability. Organizations should monitor the vendor resources for security updates. Additional technical details and research can be found at the GitHub CVE-2025-65784 Research repository.
Workarounds
- Implement server-side authorization checks that validate the authenticated user's permission to access each requested resource
- Add API gateway or reverse proxy rules to enforce object-level authorization on sensitive endpoints
- Deploy a web application firewall with rules to detect and block IDOR exploitation attempts
- Consider implementing additional authentication factors for accessing sensitive user information
- Segment sensitive user data APIs and apply stricter access controls to these endpoints
