CVE-2025-52734 is a reflected Cross-site Scripting (XSS) vulnerability identified in the ERA404 CropRefine product, affecting versions up to and including 1.2.1. The root cause is improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code into web pages viewed by other users. This vulnerability is classified as reflected XSS, meaning the malicious payload is embedded in a URL or request and reflected back in the server's response without proper sanitization. The vulnerability requires an attacker to lure a user into clicking a crafted link or submitting a malicious request, thus requiring user interaction. The CVSS v3.1 base score is 6.5, indicating medium severity, with the attack vector being network-based (remote), low attack complexity, requiring privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impacts include limited confidentiality, integrity, and availability losses, as the attacker can execute scripts in the victim's browser, potentially stealing session tokens, performing actions on behalf of the user, or causing denial of service. No known exploits are reported in the wild as of publication. The vulnerability was reserved in June 2025 and published in October 2025. No patches or mitigations are currently linked, indicating organizations must monitor vendor updates closely. Given CropRefine's role in agricultural data management, exploitation could disrupt agricultural operations or leak sensitive data.

For European organizations, especially those in the agriculture sector using ERA404 CropRefine, this vulnerability poses risks to data confidentiality, integrity, and availability. Attackers exploiting this XSS flaw could hijack user sessions, steal sensitive agricultural data, or perform unauthorized actions within the application. This could lead to operational disruptions, data leakage, and loss of trust. Since CropRefine likely manages crop data and related analytics, manipulation or exposure of this data could affect supply chain decisions and compliance with EU data protection regulations such as GDPR. The requirement for user interaction and privileges somewhat limits the attack surface but does not eliminate the risk, particularly in environments with many users or less stringent access controls. The reflected nature of the XSS also means phishing or social engineering could be used to deliver the payload. The absence of known exploits in the wild provides a window for proactive defense, but the medium severity score indicates timely remediation is important to prevent escalation or chaining with other vulnerabilities.

1. Apply patches or updates from ERA404 as soon as they become available to address this vulnerability directly. 2. Implement strict input validation and output encoding on all user-supplied data within CropRefine, especially in URL parameters and form inputs, to prevent script injection. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing CropRefine. 4. Conduct user training and awareness campaigns to recognize and avoid phishing attempts that could deliver malicious links exploiting this XSS. 5. Limit user privileges within CropRefine to the minimum necessary to reduce the impact of any successful exploitation. 6. Monitor web application logs for suspicious requests or patterns indicative of XSS attempts. 7. Use web application firewalls (WAFs) with rules tuned to detect and block reflected XSS payloads targeting CropRefine. 8. Regularly perform security testing, including automated and manual penetration tests, focusing on input handling and output encoding. 9. Isolate CropRefine instances in segmented network zones to limit lateral movement if compromised. 10. Maintain an incident response plan tailored to web application attacks involving XSS.
