CVE-2025-49402 is a Missing Authorization vulnerability (CWE-862) identified in the favethemes Houzez CRM product, affecting versions up to 1.4.7. This vulnerability arises due to incorrectly configured access control security levels, allowing users with limited privileges (requiring at least some level of authentication) to perform unauthorized actions or access data beyond their authorization scope. The CVSS 3.1 base score of 6.5 (medium severity) reflects a network exploitable vulnerability with low attack complexity, requiring privileges but no user interaction, and impacting confidentiality with no effect on integrity or availability. Specifically, an authenticated attacker with limited privileges can exploit this flaw remotely to gain unauthorized access to sensitive information within the CRM system. Since Houzez CRM is a real estate customer relationship management platform, unauthorized data disclosure could expose sensitive client information, property details, or internal business data. The vulnerability does not require user interaction but does require some level of authentication, which limits exploitation to insiders or compromised accounts. No patches or known exploits in the wild have been reported as of the publication date. The vulnerability was reserved in June 2025 and published in August 2025, indicating recent discovery and disclosure. The lack of available patches suggests that organizations using affected versions should urgently assess their exposure and implement compensating controls.

For European organizations using Houzez CRM, this vulnerability poses a significant risk to the confidentiality of sensitive customer and business data. Real estate agencies and property management firms rely heavily on CRM systems to manage client relationships, contracts, and financial information. Unauthorized access could lead to data breaches involving personal data protected under GDPR, resulting in regulatory penalties, reputational damage, and loss of client trust. Additionally, exposure of internal business data could facilitate further targeted attacks or fraud. Since the vulnerability requires authentication, the threat is heightened in environments with weak credential management or insider threats. The medium severity rating indicates a moderate but tangible risk that could be exploited by malicious insiders or attackers who have obtained valid credentials. European organizations with remote access to Houzez CRM are particularly at risk due to the network attack vector. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation. Organizations must consider the regulatory implications of data exposure under European data protection laws and the operational impact of unauthorized data access.

1. Immediate assessment of all Houzez CRM instances to identify affected versions (up to 1.4.7) and isolate or restrict access where possible. 2. Implement strict access control policies and review user privilege assignments to ensure the principle of least privilege is enforced, minimizing the number of users with elevated rights. 3. Enhance authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of credential compromise. 4. Monitor CRM access logs for unusual or unauthorized access patterns indicative of exploitation attempts. 5. Until an official patch is released, consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting access control weaknesses. 6. Conduct internal security audits and penetration tests focused on access control enforcement within the CRM environment. 7. Educate users on secure credential management and the risks of insider threats. 8. Engage with the vendor (favethemes) for timely updates and patches, and subscribe to vulnerability advisories to stay informed of developments. 9. Prepare incident response plans specific to CRM data breaches, including GDPR notification procedures.
