CVE-2025-7115 is a critical vulnerability identified in the Rowboat product developed by RowboatLabs, specifically affecting versions up to commit 8096eaf63b5a0732edd8f812bee05b78e214ee97. The vulnerability resides in the PUT method handler located in the file apps/rowboat/app/api/uploads/[fileId]/route.ts within the Session Handler component. The core issue is a missing authentication check when processing the 'params' argument, which allows an attacker to bypass authentication controls. This flaw enables remote attackers to potentially manipulate or upload files without proper authorization. The product uses continuous delivery with rolling releases, which complicates precise version tracking and patch availability. Although no known exploits are currently reported in the wild, the vulnerability's nature—remote, unauthenticated access to a critical API endpoint—makes it a significant risk. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of exploitation (no authentication or user interaction required) but limited impact on confidentiality, integrity, and availability (each rated low). The vulnerability does not require privileges or user interaction, making it easier to exploit remotely. However, the impact scope is somewhat limited by the specific functionality affected (file uploads within the session handler). The absence of a patch at the time of reporting indicates the need for immediate attention and monitoring for updates from RowboatLabs.

For European organizations using RowboatLabs' Rowboat product, this vulnerability poses a tangible risk of unauthorized access to file upload functionalities, potentially leading to unauthorized data manipulation, injection of malicious files, or disruption of service components relying on session handling. Given the unauthenticated nature of the exploit, attackers could leverage this vulnerability to compromise internal systems, exfiltrate sensitive data, or establish footholds for further attacks. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face regulatory repercussions under GDPR if exploited. Additionally, the ability to remotely exploit this vulnerability without authentication increases the risk of widespread automated attacks, especially if threat actors develop exploit tools. The continuous delivery model used by RowboatLabs means that organizations must be vigilant in tracking updates and patches, as the vulnerability may be fixed in future releases without clear versioning. This uncertainty complicates vulnerability management and patch deployment strategies. Overall, the vulnerability could undermine trust in affected applications, cause operational disruptions, and expose organizations to data breaches or compliance violations.

1. Immediate mitigation should include implementing network-level access controls to restrict access to the vulnerable PUT endpoint, such as IP whitelisting or VPN requirements, to limit exposure to trusted users only. 2. Employ Web Application Firewalls (WAFs) with custom rules to detect and block anomalous or unauthorized PUT requests targeting the uploads API path. 3. Monitor application logs closely for unusual or unauthorized access attempts to the uploads endpoint, enabling rapid detection and response. 4. Engage with RowboatLabs to obtain timely information on patches or updates addressing this vulnerability; prioritize testing and deployment of any forthcoming fixes. 5. As a temporary workaround, if feasible, disable or restrict the uploads API endpoint until a patch is available. 6. Conduct thorough security reviews of session handling and authentication mechanisms within the application to identify and remediate similar issues proactively. 7. Educate development and operations teams about the risks of missing authentication checks in API endpoints, emphasizing secure coding and review practices. 8. Implement multi-factor authentication and strong authorization checks for all sensitive API operations to reduce the risk of unauthorized access.
