CVE-2025-62911 identifies a Stored Cross-site Scripting (XSS) vulnerability in Rock Content's Rock Convert product, versions up to and including 3.0.1. The vulnerability stems from improper neutralization of user input during the generation of web pages, allowing malicious scripts to be stored and later executed in the browsers of users who view the affected content. This type of vulnerability is particularly dangerous because it can persist on the server and affect multiple users without requiring repeated exploitation. The CVSS 3.1 base score is 5.4 (medium), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), user interaction (UI:R), and a scope change (S:C). The impact affects confidentiality and integrity partially (C:L/I:L), but does not affect availability (A:N). The requirement for privileges and user interaction suggests that an attacker must have some level of access to the system and trick a user into triggering the malicious payload. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and should be addressed promptly. The lack of available patches at the time of publication necessitates interim mitigations. Stored XSS can be leveraged for session hijacking, credential theft, or delivering further malware, posing significant risks to organizations relying on Rock Convert for content management or marketing automation.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive information and manipulation of content integrity within Rock Convert environments. Attackers exploiting the stored XSS could hijack user sessions, steal authentication tokens, or perform actions on behalf of legitimate users, potentially leading to data breaches or unauthorized changes in marketing campaigns or customer-facing content. The impact is heightened in sectors with strict data protection regulations such as GDPR, where leakage of personal data could result in regulatory penalties and reputational damage. Since Rock Convert is used primarily in digital marketing and content conversion, organizations relying heavily on these functions may face operational disruptions and loss of customer trust. The requirement for privileges and user interaction limits the attack surface but does not eliminate risk, especially in environments with multiple users or third-party contributors. The absence of known exploits in the wild reduces immediate risk but does not preclude targeted attacks, particularly from advanced persistent threat actors focusing on marketing infrastructure.

Organizations should immediately review user privilege assignments within Rock Convert to minimize the number of users with write or content submission capabilities. Implement strict input validation and output encoding on all user-generated content to neutralize malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Monitor logs and user activity for unusual content submissions or script injections. Educate users about the risks of interacting with untrusted content and phishing attempts that could trigger the stored XSS payload. Coordinate with Rock Content for timely patch releases and apply updates as soon as they become available. If patches are not yet available, consider isolating the Rock Convert environment or restricting access to trusted users only. Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including XSS. Finally, integrate web application firewalls (WAFs) with custom rules to detect and block suspicious input patterns related to XSS attacks.
