CVE-2025-10196 is a stored Cross-Site Scripting (XSS) vulnerability identified in the Survey Anyplace plugin for WordPress, affecting all versions up to and including 1.0.0. The vulnerability arises from improper neutralization of input during web page generation, specifically within the 'surveyanyplace_embed' shortcode. Authenticated users with contributor-level access or higher can supply malicious input that is insufficiently sanitized and escaped, allowing arbitrary JavaScript code to be stored and subsequently executed in the context of any user who views the compromised page. This persistent XSS flaw can be exploited to hijack user sessions, steal cookies, perform actions on behalf of users, or deliver further payloads. The vulnerability is remotely exploitable over the network without user interaction but requires authenticated access with limited privileges, which lowers the attack barrier compared to administrator-only flaws. The CVSS v3.1 base score is 6.4, reflecting medium severity with low attack complexity, partial confidentiality and integrity impact, and no availability impact. No known public exploits or patches are currently available, increasing the urgency for organizations to implement compensating controls. The vulnerability is cataloged under CWE-79, highlighting the failure to properly sanitize and escape user-supplied input in web applications. Given the widespread use of WordPress and the plugin’s functionality for embedding surveys, this vulnerability poses a risk to websites that rely on Survey Anyplace for interactive content.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to user sessions, data leakage, and potential defacement or manipulation of website content. Since the attack requires contributor-level access, insider threats or compromised accounts could be leveraged to inject malicious scripts. This could undermine trust in affected websites, lead to reputational damage, and expose sensitive user information, particularly in sectors like education, government, and enterprises that use Survey Anyplace for surveys and data collection. The persistent nature of the XSS means that any visitor to the infected pages could be impacted, amplifying the scope of the attack. Additionally, attackers could use this foothold to pivot to more severe attacks such as privilege escalation or malware distribution. The medium severity rating suggests a moderate but non-negligible risk, especially for organizations with multiple contributors or less stringent access controls. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability is publicized.

European organizations should immediately audit user roles and permissions within WordPress to ensure that contributor-level access is granted only to trusted users. Restricting the number of users who can add or edit shortcodes reduces the attack surface. Until an official patch is released, implement custom input validation and output escaping for the 'surveyanyplace_embed' shortcode, possibly via WordPress hooks or security plugins that sanitize shortcode attributes. Monitor website content for unauthorized script injections and unusual shortcode usage. Employ Web Application Firewalls (WAFs) with rules targeting XSS payloads in shortcode parameters. Educate content contributors about the risks of injecting untrusted content. Regularly update WordPress core and plugins to the latest versions once patches become available. Consider isolating or disabling the Survey Anyplace plugin if it is not essential. Finally, maintain robust logging and incident response plans to detect and respond to any exploitation attempts promptly.
