CVE-2025-62516 is a critical security vulnerability identified in the TurboTenant landlord onboarding and rental signup product, specifically affecting versions 2.0.0 and earlier. The vulnerability is categorized under CWE-200, indicating exposure of sensitive information to unauthorized actors. The root cause lies in the property listing activation workflow and associated API endpoints responsible for subscription metadata and payment link generation. These endpoints improperly handle access controls, allowing unauthenticated, remote attackers to retrieve sensitive Stripe payment session data. This data includes business metadata related to landlords’ dashboard synchronization and tenant personal information, which should be strictly protected. The vulnerability is remotely exploitable without any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is critical, affecting confidentiality, integrity, and availability, with a CVSS score of 9.8. While no public exploits have been reported, the potential for abuse is high due to the nature of the exposed data, which could facilitate financial fraud, identity theft, and unauthorized access to rental management systems. The vulnerability affects the API layer of the TurboTenant platform, a SaaS solution widely used in property rental markets. The lack of patch links suggests that fixes may still be pending or in development, emphasizing the need for immediate risk mitigation by affected users.

For European organizations, the impact of CVE-2025-62516 is significant. Exposure of Stripe payment session data and tenant information can lead to severe privacy breaches, violating GDPR and other data protection regulations, resulting in substantial fines and reputational damage. Unauthorized access to landlord dashboard sync details may allow attackers to manipulate rental listings, disrupt business operations, or conduct fraudulent transactions. The compromise of payment session data could facilitate financial fraud, including unauthorized charges or theft of payment credentials. Given the critical severity and ease of exploitation, organizations relying on TurboTenant for property management risk operational disruption and loss of customer trust. Additionally, the exposure of tenant personal data could lead to identity theft and legal liabilities. The vulnerability’s presence in a core workflow means that many tenants and landlords could be affected simultaneously, amplifying the potential damage. European real estate firms, property managers, and rental platforms using TurboTenant must consider this a high-priority threat.

Until an official patch is released, European organizations should implement immediate compensating controls. These include restricting API access through network-level controls such as IP whitelisting and VPN requirements to limit exposure to trusted users only. Implement strict monitoring and logging of API calls related to property listing activation and payment session handling to detect anomalous access patterns. Review and tighten API authentication and authorization mechanisms, ensuring that sensitive endpoints require proper credentials and role-based access controls. Engage with TurboTenant support to obtain any available interim fixes or guidance. Conduct a thorough audit of all Stripe payment session data and landlord dashboard synchronization logs to identify potential data leaks. Educate internal teams about the vulnerability and enforce strict data handling policies. Finally, prepare incident response plans to quickly address any detected exploitation attempts. Once patches become available, prioritize immediate deployment and verify remediation through penetration testing.
