CVE-2025-6247 is a security vulnerability identified in the WordPress Automatic Plugin developed by ValvePress. This plugin is widely used to automate content posting on WordPress sites. The vulnerability is classified as CWE-80, indicating improper neutralization of script-related HTML tags, which is a basic Cross-Site Scripting (XSS) issue. Specifically, the vulnerability arises from a Cross-Site Request Forgery (CSRF) flaw due to missing or incorrect nonce validation in one of the plugin's functions. Nonces in WordPress are security tokens used to verify that requests are intentional and originate from legitimate users. The absence or misconfiguration of nonce validation allows unauthenticated attackers to craft malicious requests that can update campaigns within the plugin. If an attacker successfully tricks a site administrator into clicking a malicious link, they can inject arbitrary web scripts into the site. This injection can lead to the execution of malicious JavaScript in the context of the administrator's browser, potentially compromising session tokens, redirecting users, or performing unauthorized actions. The vulnerability affects all versions of the plugin up to and including version 3.118.0. The CVSS v3.1 base score is 4.7, reflecting a medium severity level. The vector indicates that the attack can be launched remotely (AV:N) with high attack complexity (AC:H), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact is limited to low confidentiality and integrity impacts (C:L/I:L) with no availability impact (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet, which suggests that mitigation may rely on plugin updates or manual intervention once available.

For European organizations, this vulnerability poses a risk primarily to websites using the WordPress Automatic Plugin, which is popular among content-heavy sites, marketing agencies, and e-commerce platforms. Successful exploitation could allow attackers to inject malicious scripts that compromise site administrators' sessions, potentially leading to unauthorized content modifications, defacement, or further pivoting into internal networks if administrative credentials are stolen. This can damage brand reputation, lead to data leakage, and cause regulatory compliance issues under GDPR if personal data is exposed or manipulated. The requirement for user interaction (administrator clicking a malicious link) somewhat limits the attack vector but does not eliminate risk, especially in environments where phishing attacks are common. The changed scope indicates that the impact could extend beyond the plugin to other parts of the WordPress site or connected systems. Given the widespread use of WordPress across Europe, the vulnerability could affect a broad range of sectors including government, finance, healthcare, and media, where WordPress is used for public-facing websites and internal portals.

European organizations should immediately audit their WordPress installations to identify the presence of the ValvePress WordPress Automatic Plugin and verify the version in use. Until an official patch is released, administrators should consider disabling or uninstalling the plugin to eliminate the attack surface. If disabling is not feasible, strict access controls should be enforced to limit administrative user exposure to phishing attempts, including multi-factor authentication (MFA) and user training focused on recognizing social engineering attacks. Web Application Firewalls (WAFs) can be configured to detect and block suspicious requests targeting the plugin's vulnerable endpoints. Monitoring logs for unusual campaign update activities or unexpected POST requests can help detect exploitation attempts. Once a patch is available, prompt application of updates is critical. Additionally, implementing Content Security Policy (CSP) headers can reduce the impact of injected scripts by restricting script execution sources. Regular backups and incident response plans should be reviewed to prepare for potential exploitation scenarios.
