CVE-2025-46690 is a security vulnerability classified under CWE-425 (Direct Request, also known as Forced Browsing) affecting Ververica Platform version 2.14.0. The vulnerability allows low-privileged users to access SQL connectors by directly requesting the endpoint namespaces/default/formats. This means that an attacker with limited permissions can bypass intended access controls and retrieve or interact with SQL connector resources that should otherwise be restricted. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N). The attack complexity is low (AC:L), and the attacker must have some privileges (PR:L), but no UI interaction is needed (UI:N). The scope is changed (S:C), indicating that exploitation affects resources beyond the initially vulnerable component. The impact is limited to integrity (I:L) with no impact on confidentiality (C:N) or availability (A:N). This suggests that while attackers cannot read sensitive data or disrupt service availability, they can modify or manipulate SQL connector configurations or data, potentially leading to unauthorized changes in the platform's operation or data processing pipelines. No known exploits are currently reported in the wild, and no patches are listed yet. The vulnerability was published on April 27, 2025, and is assigned a CVSS v3.1 base score of 5.0, categorized as medium severity. The Ververica Platform is a data streaming and processing platform used primarily in enterprise environments for managing Apache Flink clusters and connectors, which are critical for real-time data processing workflows.

For European organizations, especially those leveraging the Ververica Platform for real-time data streaming and analytics, this vulnerability poses a moderate risk. Unauthorized modification of SQL connectors could lead to data integrity issues, such as incorrect data being processed or routed, potentially impacting business decisions or automated processes relying on accurate data streams. While confidentiality and availability are not directly impacted, the integrity compromise could result in operational disruptions or compliance issues, particularly in regulated sectors like finance, telecommunications, and critical infrastructure. Organizations with multi-tenant environments or shared access models are at higher risk, as low-privileged users might exploit this vulnerability to escalate their influence within the platform. Given the platform’s role in data pipelines, any unauthorized changes could propagate downstream, affecting data quality and trustworthiness. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

1. Implement strict access control policies limiting user privileges to the minimum necessary, ensuring that low-privileged users cannot access sensitive endpoints even via direct requests. 2. Monitor and log all access to the namespaces/default/formats endpoint to detect unusual or unauthorized access patterns promptly. 3. Employ web application firewalls (WAFs) with custom rules to detect and block forced browsing attempts targeting the vulnerable endpoint. 4. Conduct regular security assessments and penetration tests focusing on direct request vulnerabilities and access control weaknesses within the Ververica Platform. 5. Segregate environments and sensitive connectors to reduce the blast radius in case of exploitation. 6. Stay updated with Ververica’s security advisories and apply patches or updates as soon as they become available. 7. If possible, implement network-level segmentation to restrict access to the Ververica Platform management interfaces to trusted administrative networks only. 8. Educate users about the risks of privilege escalation and enforce strong authentication and authorization mechanisms to reduce the risk of compromised low-privileged accounts being used for exploitation.
