CVE-2025-7050 is a stored cross-site scripting (XSS) vulnerability identified in the Use-your-Drive | Google Drive plugin for WordPress, maintained by WP Cloud Plugins/_deleeuw_. The vulnerability stems from improper neutralization of input during web page generation (CWE-79), specifically inadequate sanitization and escaping of the 'title' parameter within file metadata. This flaw affects all plugin versions up to and including 3.3.1. An attacker can exploit this vulnerability by uploading a file with a crafted 'title' containing malicious JavaScript code. Because the plugin allows file uploads via shortcodes embedded in publicly accessible posts, the malicious script is stored and served to any user visiting the page, executing in their browser context. Notably, exploitation requires no authentication (PR:N) and no user interaction (UI:N), making it highly accessible. The vulnerability impacts confidentiality and integrity by enabling theft of cookies, session tokens, or execution of arbitrary actions on behalf of the victim. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N) indicates network attack vector, low attack complexity, no privileges or user interaction required, and scope change due to cross-site scripting. Although no public exploits are known yet, the vulnerability poses a significant risk to WordPress sites using this plugin, especially those allowing file uploads from untrusted users. The lack of available patches at the time of publication necessitates immediate mitigation steps to prevent exploitation.

The impact of CVE-2025-7050 is substantial for organizations using the vulnerable Use-your-Drive plugin on WordPress sites. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of the victim's browser, potentially leading to session hijacking, credential theft, unauthorized actions, and further compromise of user accounts or site integrity. Since the vulnerability can be triggered by unauthenticated users uploading files, it significantly lowers the barrier for attackers, increasing the likelihood of exploitation. This can result in data breaches, defacement, or distribution of malware to site visitors, damaging organizational reputation and trust. For multi-tenant or high-traffic websites, the risk escalates as more users may be exposed. Additionally, the scope change indicated by the CVSS vector means that the vulnerability can affect resources beyond the plugin itself, potentially impacting the entire WordPress site and its users. The absence of known exploits currently provides a window for remediation, but the ease of exploitation and widespread use of WordPress and this plugin amplify the threat globally.

To mitigate CVE-2025-7050, organizations should immediately: 1) Update the Use-your-Drive plugin to a patched version once released by the vendor; 2) Until a patch is available, disable or remove the file upload shortcode from publicly accessible posts to prevent malicious file uploads; 3) Restrict file upload permissions strictly to trusted, authenticated users and consider disabling uploads from unauthenticated users; 4) Implement Web Application Firewall (WAF) rules to detect and block suspicious payloads targeting the 'title' parameter or file metadata fields; 5) Employ Content Security Policy (CSP) headers to limit the execution of inline scripts and reduce XSS impact; 6) Regularly audit uploaded files and metadata for suspicious content; 7) Educate site administrators on the risks of allowing file uploads from untrusted sources; 8) Monitor site logs for unusual activity related to file uploads or script execution. These steps go beyond generic advice by focusing on immediate containment and layered defenses until official patches are deployed.
