CVE-2026-0588 describes a cross-site scripting (XSS) vulnerability within Rainrock RockOA versions 2.7.0 through 2.7.1. This flaw resides in the rockfun.php file within the API component, allowing attackers to inject malicious scripts. Successful exploitation could lead to unauthorized access and manipulation of user data. A public proof-of-concept is available, indicating a potential for active exploitation.
The XSS vulnerability in Rainrock RockOA allows an attacker to inject arbitrary JavaScript code into web pages viewed by other users. This can be leveraged to steal session cookies, redirect users to malicious websites, or deface the application. The impact is amplified if the application is used by a large number of users or handles sensitive data. Given the availability of a public proof-of-concept, the risk of exploitation is considered significant. Attackers could potentially gain control of user accounts or compromise the entire application server if the injected script has sufficient privileges.
CVE-2026-0588 has been publicly disclosed and a proof-of-concept is available, indicating a high probability of exploitation. The vulnerability was reported on 2026-01-05. The vendor has not responded to early disclosure attempts. The CVSS score is LOW, but the public availability of a PoC elevates the risk.

The primary mitigation for CVE-2026-0588 is to upgrade Rainrock RockOA to a patched version. As no fixed version is specified, contact the vendor for an updated release. In the interim, implement input validation and output encoding on all user-supplied data within the rockfun.php component. Consider using a Web Application Firewall (WAF) to filter out malicious requests containing JavaScript payloads. Regularly scan the application for XSS vulnerabilities using automated tools.
Actualizar Rainrock RockOA a una versión posterior a 2.7.1. Si no hay actualizaciones disponibles, considerar deshabilitar o eliminar el componente afectado (rockfun.php) hasta que se publique una solución. Alternativamente, implementar medidas de seguridad como la validación y el saneamiento de la entrada 'callback' para prevenir ataques XSS.
