CVE-2025-59137 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the eLEOPARD Behance Portfolio Manager, a tool used for managing creative portfolios. The vulnerability exists in versions up to 1.7.5 and allows attackers to trick authenticated users into submitting unauthorized requests to the application. This can lead to stored Cross-Site Scripting (XSS) attacks, where malicious scripts are injected and persist within the application, potentially compromising user sessions and data. The vulnerability is exploitable remotely without authentication but requires user interaction, such as clicking a crafted link or visiting a malicious website. The CVSS 3.1 base score of 7.1 reflects the high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable part, potentially impacting other users or systems. No patches or known exploits are currently available, increasing the urgency for proactive mitigation. The vulnerability stems from inadequate CSRF protections, such as missing or ineffective anti-CSRF tokens and insufficient validation of request origins, allowing attackers to perform actions on behalf of users without their consent.

For European organizations, this vulnerability poses significant risks including unauthorized changes to portfolio content, injection of malicious scripts leading to session hijacking or data theft, and potential disruption of service availability. Organizations relying on eLEOPARD Behance Portfolio Manager for showcasing creative work or managing client portfolios could suffer reputational damage and loss of customer trust if exploited. The stored XSS component can facilitate further attacks such as credential theft or spreading malware within corporate networks. Given the remote exploitability and lack of authentication requirements, attackers can target a broad range of users, increasing the attack surface. The impact extends to confidentiality, integrity, and availability of data, potentially affecting compliance with GDPR and other data protection regulations. Additionally, the vulnerability could be leveraged in targeted attacks against high-profile creative agencies or freelancers, which are prevalent in Europe’s digital economy.

European organizations should immediately review their use of eLEOPARD Behance Portfolio Manager and implement compensating controls. These include enforcing strict CSRF protections by integrating anti-CSRF tokens in all state-changing requests and validating the Origin and Referer headers to ensure requests originate from trusted sources. Organizations should conduct thorough code audits to identify and remediate stored XSS vulnerabilities, sanitize all user inputs, and implement Content Security Policy (CSP) headers to mitigate script injection impacts. Monitoring and logging of unusual user activities and request patterns can help detect exploitation attempts early. Until an official patch is released, consider restricting access to the portfolio manager to trusted networks or users and educating users about the risks of clicking unknown links. Regular backups and incident response plans should be updated to address potential exploitation scenarios. Collaboration with eLEOPARD for timely patching and updates is critical.
