CVE-2025-62755 is a vulnerability identified in the GS Portfolio for Envato plugin, versions up to 1.4.2, which is used primarily in WordPress environments to showcase portfolios. The vulnerability is classified under CWE-862, indicating missing authorization controls. Specifically, the plugin fails to verify whether a user has the necessary permissions before allowing access to certain functionalities or data. This missing authorization is exploitable by unauthenticated attackers over the network, as no privileges or user interaction are required. The flaw allows attackers to perform unauthorized actions that can alter data integrity, such as modifying portfolio content or configurations, potentially leading to misinformation or defacement. The CVSS v3.1 base score of 5.3 reflects a medium severity, with attack vector being network-based, low attack complexity, no privileges required, no user interaction, and impact limited to integrity without affecting confidentiality or availability. No public exploits or patches are currently available, but the vulnerability is officially published and reserved as of late 2025. The plugin’s widespread use in creative and digital agencies makes this a notable risk, particularly for organizations relying on Envato’s ecosystem for portfolio presentation. The lack of authorization checks is a fundamental security oversight that can be leveraged for unauthorized modifications, potentially damaging organizational reputation and trust.

For European organizations, the impact of this vulnerability can be significant, especially for those using the GS Portfolio for Envato plugin to manage client-facing portfolios or internal project showcases. Unauthorized modifications could lead to data integrity issues, such as altered or malicious content being displayed publicly, which can harm brand reputation and client trust. Although confidentiality and availability are not directly impacted, the integrity breach could facilitate further social engineering or phishing attacks by presenting misleading information. Organizations in sectors like digital marketing, creative agencies, and freelance professionals are particularly at risk. The ease of exploitation without authentication increases the threat level, as attackers can operate remotely without needing credentials. This vulnerability could also be leveraged as a foothold for more advanced attacks if combined with other vulnerabilities in the hosting environment. Given the plugin’s integration with WordPress, a widely used CMS in Europe, the scope of affected systems is broad, potentially impacting thousands of websites. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks.

European organizations should implement several specific mitigations beyond generic patching advice. First, immediately restrict access to the plugin’s administrative and API endpoints using web application firewalls (WAFs) or server-level access controls to limit exposure to unauthenticated users. Employ strict IP whitelisting or VPN requirements for accessing backend interfaces where feasible. Monitor web server and application logs for unusual requests targeting GS Portfolio plugin endpoints to detect potential exploitation attempts early. Implement Content Security Policy (CSP) and Subresource Integrity (SRI) to reduce the impact of any unauthorized content modifications. Until an official patch is released, consider disabling or uninstalling the GS Portfolio plugin if it is not critical to operations. For organizations that must continue using the plugin, isolate the hosting environment with network segmentation to reduce lateral movement risks. Regularly back up portfolio data and website content to enable quick restoration in case of compromise. Engage with the vendor or community to track patch releases and apply updates promptly once available. Finally, conduct security awareness training for web administrators to recognize and respond to signs of exploitation.
