CVE-2025-62755 identifies a missing authorization vulnerability (CWE-862) in the GS Portfolio for Envato WordPress plugin, specifically in versions up to 1.4.2. The vulnerability arises because the plugin fails to properly verify whether a user is authorized before allowing certain actions, effectively enabling unauthenticated users to perform operations that should be restricted. This broken access control flaw can be exploited remotely without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is limited to integrity, meaning attackers could modify or manipulate data or plugin behavior, but confidentiality and availability remain unaffected. No known public exploits or patches are currently available, but the vulnerability has been officially published and reserved in late 2025. The plugin is commonly used by creative professionals and agencies to showcase portfolios on WordPress sites, making it a target for attackers seeking to deface websites or inject malicious content. The absence of authentication requirements lowers the barrier for exploitation, increasing the risk to affected sites. The vulnerability's medium severity score (5.3) reflects the moderate risk posed by the integrity impact combined with ease of exploitation and lack of authentication requirements.

For European organizations, the primary impact of CVE-2025-62755 is the potential unauthorized modification of website content or portfolio data managed through the GS Portfolio for Envato plugin. This could lead to reputational damage, misinformation, or the injection of malicious content that could further compromise visitors or users. Organizations in sectors relying heavily on digital portfolios, such as creative agencies, marketing firms, and freelancers, may experience disruptions or loss of client trust. Since the vulnerability does not affect confidentiality or availability, direct data breaches or service outages are less likely. However, integrity compromises can indirectly lead to broader security incidents if attackers leverage modified content to distribute malware or phishing links. The ease of exploitation without authentication increases the risk of widespread attacks, especially on publicly accessible WordPress sites. European entities with limited patch management capabilities or those unaware of the vulnerability may be particularly vulnerable. The lack of known exploits currently provides a window for proactive mitigation before active exploitation occurs.

1. Monitor official GS Plugins and Envato channels for the release of security patches addressing CVE-2025-62755 and apply updates promptly once available. 2. Until patches are released, implement web application firewall (WAF) rules to restrict or monitor suspicious requests targeting the GS Portfolio plugin endpoints. 3. Employ strict access control policies on WordPress admin and plugin management interfaces, limiting permissions to trusted users only. 4. Conduct regular security audits and integrity checks of portfolio content to detect unauthorized modifications early. 5. Disable or remove the GS Portfolio plugin if it is not essential to reduce the attack surface. 6. Use security plugins that can detect and alert on anomalous behavior or unauthorized changes within WordPress environments. 7. Educate site administrators about the risks of broken access control and encourage best practices in plugin management and security hygiene. 8. Consider network segmentation or isolation for critical web assets to limit the impact of potential compromises.
