CVE-2025-32896:
Java vulnerability analysis and mitigation
Overview
Apache SeaTunnel versions 2.3.1 through 2.3.10 contain a vulnerability (CVE-2025-32896) that allows unauthorized users to exploit insecure REST API endpoints. The vulnerability was discovered in early April 2025 and affects the legacy REST API v1 endpoint. This security flaw enables attackers to perform arbitrary file read operations and potentially execute remote code through deserialization attacks (Apache List, Security Online).
Technical details
The vulnerability stems from unauthenticated access to the legacy REST API v1 endpoint '/hazelcast/rest/maps/submit-job'. Attackers can exploit this endpoint by submitting jobs to SeaTunnel without proper authentication. The vulnerability can be triggered by injecting malicious parameters in the MySQL connection URL, leading to arbitrary file reads and unsafe Java object deserialization. The severity has been classified as moderate to critical depending on deployment context (GBHackers).
Impact
The vulnerability enables attackers to access sensitive files on the server, including configuration files and credentials. Through Java deserialization exploitation, attackers may achieve remote code execution (RCE), potentially gaining full control over the affected server. Given SeaTunnel's widespread adoption by large enterprises for data synchronization, the potential impact is significant (GBHackers).
Mitigation and workarounds
The Apache SeaTunnel team has addressed the vulnerability in version 2.3.11. Users are strongly advised to upgrade to this version or later, disable RESTful API v1, and switch to API v2 which enforces stricter authentication. Additionally, it is recommended to enable HTTPS two-way authentication for all SeaTunnel nodes to ensure secure communication and prevent unauthorized access (GBHackers, Apache List).
