CVE-2025-57164 identifies a remote code execution (RCE) vulnerability in Flowise, a software product used for workflow automation and integration, specifically up to version 3.0.4. The vulnerability arises from the unsanitized evaluation of user input within the 'Supabase RPC Filter' field, which is designed to allow users to specify filters for remote procedure calls (RPCs) to Supabase, a backend-as-a-service platform. Because the input is not properly sanitized or validated, an attacker can inject malicious code that the system evaluates, leading to arbitrary code execution on the host running Flowise. This flaw does not require authentication or user interaction, making it highly exploitable remotely. The vulnerability was reserved in August 2025 and published in October 2025, but no CVSS score or public exploit code is currently available. The lack of patches or mitigations at the time of publication increases the risk for organizations using vulnerable versions. The vulnerability impacts the confidentiality, integrity, and availability of systems, as attackers can execute arbitrary commands, potentially leading to data breaches, system compromise, or denial of service. Flowise’s integration with Supabase means that organizations leveraging this stack for backend services are particularly exposed. The absence of CWE classification and patch links suggests early disclosure or incomplete analysis, emphasizing the need for immediate attention from users and developers.

For European organizations, the impact of CVE-2025-57164 can be severe. Organizations using Flowise in their automation or backend workflows, especially those integrating Supabase services, face the risk of remote attackers executing arbitrary code on critical infrastructure. This can lead to unauthorized data access, data manipulation, service disruption, and potential lateral movement within networks. Given the increasing reliance on cloud services and automation tools in Europe’s digital economy, exploitation could affect sectors such as finance, healthcare, government, and technology. The vulnerability could undermine trust in digital services and cause regulatory compliance issues under GDPR if personal data is compromised. Additionally, the lack of available patches or mitigations at the time of disclosure increases exposure time. The potential for widespread impact is heightened if attackers develop exploit tools, given the vulnerability’s remote and unauthenticated nature.

To mitigate CVE-2025-57164, organizations should immediately audit their use of Flowise, particularly versions up to 3.0.4, and identify any deployment that uses the 'Supabase RPC Filter' feature. Until an official patch is released, implement strict input validation and sanitization on all user inputs related to RPC filters to prevent code injection. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the RPC filter. Restrict access to Flowise interfaces to trusted networks and authenticated users where possible to reduce exposure. Monitor logs for unusual activity or errors related to RPC filter processing. Engage with Flowise vendors or community to obtain updates or patches promptly. Consider isolating or containerizing Flowise instances to limit the blast radius of potential exploitation. Finally, educate developers and administrators about secure coding practices to prevent similar injection vulnerabilities in the future.
