CVE-2026-22445 identifies a missing authorization vulnerability in the Proptech Plugin Apimo Connector, affecting versions up to and including 2.6.4. The root cause is an incorrectly configured access control mechanism that fails to properly restrict access to certain functionalities or data endpoints within the plugin. This flaw allows an unauthenticated attacker to remotely access data that should be protected, without requiring any user interaction or prior authentication. The vulnerability is exploitable over the network with low attack complexity, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is limited to confidentiality, with no direct effect on data integrity or availability. The plugin is commonly used in property technology platforms to integrate with Apimo real estate data services, making it a critical component in Proptech ecosystems. Although no public exploits have been reported, the exposure of sensitive property or client data could lead to privacy violations, competitive disadvantage, or regulatory non-compliance. The lack of patches or vendor advisories necessitates immediate attention to access control configurations and monitoring. Given the plugin's role in handling real estate data, unauthorized data disclosure could affect business operations and client trust.

For European organizations, especially those in the real estate and Proptech sectors, this vulnerability poses a risk of unauthorized data disclosure. Confidential client information, property listings, or transactional data could be exposed, potentially violating GDPR and other data protection regulations. This could result in legal penalties, reputational damage, and loss of customer trust. Although the vulnerability does not allow data modification or service disruption, the confidentiality breach alone is significant given the sensitivity of real estate data. Organizations relying on the Apimo Connector for integrating property data services are at risk of targeted reconnaissance or data harvesting attacks. The medium severity rating suggests a moderate but actionable threat, particularly for companies with large volumes of sensitive property data or those operating in competitive markets. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks. European firms must consider the regulatory implications and the strategic importance of protecting client and property information.

1. Immediately review and audit access control configurations within the Apimo Connector plugin to ensure that all sensitive endpoints require proper authorization. 2. Restrict network access to the plugin interfaces by implementing IP whitelisting or VPN access where feasible. 3. Monitor logs and network traffic for unusual or unauthorized access attempts targeting the plugin. 4. Engage with the plugin vendor or Proptech Plugin maintainers to obtain patches or security updates addressing this vulnerability. 5. If patches are unavailable, implement compensating controls such as web application firewalls (WAF) with rules to block unauthorized requests. 6. Conduct regular security assessments and penetration tests focusing on Proptech integrations to detect similar misconfigurations. 7. Educate IT and security teams about the risks associated with missing authorization vulnerabilities and enforce strict change management for plugin updates. 8. Ensure compliance with GDPR by promptly reporting any data breaches resulting from exploitation and maintaining transparent communication with affected stakeholders.
