CVE-2025-68998 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Heateor Social Login plugin, a WordPress extension that facilitates user authentication via social media accounts. The vulnerability exists in versions up to and including 1.1.39, allowing attackers to craft malicious web requests that, when visited by an authenticated user, cause the victim's browser to perform unintended actions on the affected website. The vulnerability leverages the absence or improper implementation of anti-CSRF tokens or other request validation mechanisms. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N), the attack can be launched remotely over the network with low attack complexity, requires no privileges, but does require user interaction (such as clicking a link). The impact is limited to confidentiality and integrity, potentially allowing attackers to manipulate user data or session information without causing denial of service. No known exploits are currently reported in the wild, and no patches or mitigation links have been published yet. The vulnerability was publicly disclosed on December 30, 2025, by Patchstack. Given the plugin's role in authentication workflows, successful exploitation could undermine user trust and lead to unauthorized actions within web applications relying on this plugin.

For European organizations, the CSRF vulnerability in Heateor Social Login could lead to unauthorized actions performed on behalf of legitimate users, such as changing user settings, linking or unlinking social accounts, or other state-changing operations permitted by the plugin. While the direct impact on confidentiality and integrity is limited, the exploitation could facilitate further attacks like session hijacking or privilege escalation if combined with other vulnerabilities. Organizations operating e-commerce, social networking, or membership sites using this plugin are particularly at risk. The absence of availability impact reduces the risk of service disruption, but reputational damage and potential data exposure remain concerns. Given the medium CVSS score and requirement for user interaction, the threat level is moderate but should not be underestimated, especially in environments with high user engagement and sensitive data.

1. Monitor the vendor's official channels for patches addressing CVE-2025-68998 and apply updates promptly once available. 2. In the interim, implement web application firewall (WAF) rules to detect and block suspicious CSRF attack patterns targeting the plugin endpoints. 3. Enforce strict SameSite cookie attributes to reduce the risk of CSRF attacks via cross-site requests. 4. Validate the presence and correctness of anti-CSRF tokens in all state-changing requests within the plugin's codebase if custom modifications are possible. 5. Educate users to avoid clicking on suspicious links, especially when logged into critical web applications using this plugin. 6. Conduct security audits and penetration testing focusing on authentication and session management components to identify any chained vulnerabilities. 7. Consider disabling or replacing the plugin temporarily if no patch is available and the risk is deemed unacceptable.
