CVE-2025-48363 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'Popup for CF7 with Sweet Alert' developed by Metin Saraç. This plugin integrates popup functionality with the Contact Form 7 (CF7) plugin using Sweet Alert for enhanced user interaction. The vulnerability affects versions up to and including 1.6.5. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request unknowingly, exploiting the user's active session and privileges. In this case, the vulnerability allows an attacker to perform unauthorized actions on behalf of the user without their consent or interaction beyond visiting a crafted web page. The CVSS v3.1 base score is 4.3 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact is limited to integrity (I:L) with no confidentiality or availability impact. There are no known exploits in the wild currently, and no patches have been linked yet. The vulnerability is categorized under CWE-352, which is a common web application security weakness related to CSRF. Since the plugin is widely used in WordPress environments that utilize CF7 for form management, this vulnerability could be leveraged to manipulate form submissions or popup behaviors maliciously, potentially leading to unauthorized changes in site behavior or data manipulation within the scope of the plugin's functionality.

For European organizations using WordPress websites with the 'Popup for CF7 with Sweet Alert' plugin, this vulnerability poses a moderate risk. While it does not directly compromise confidentiality or availability, the integrity impact could allow attackers to alter form submissions or popup configurations, potentially leading to misinformation, unauthorized data entry, or manipulation of user interactions. This could affect customer trust, data accuracy, and site functionality. Organizations in sectors with high reliance on web forms for customer interaction, such as e-commerce, healthcare, and public services, may face reputational damage or operational disruptions. Additionally, if attackers chain this vulnerability with others, it could facilitate more severe attacks. Given the plugin's integration with CF7, which is popular in Europe, the risk is non-negligible. However, the requirement for user interaction and the absence of privilege requirements somewhat limit the exploitability scope.

European organizations should immediately audit their WordPress installations to identify the presence of the 'Popup for CF7 with Sweet Alert' plugin, especially versions up to 1.6.5. Until an official patch is released, administrators should consider disabling or removing the plugin to eliminate exposure. Implementing anti-CSRF tokens and verifying the origin of requests within the plugin's code can mitigate the vulnerability; organizations with development resources may apply temporary custom patches or workarounds. Additionally, educating users to avoid clicking on suspicious links and monitoring web traffic for unusual POST requests related to the plugin can help detect exploitation attempts. Employing Web Application Firewalls (WAFs) with rules to block CSRF attack patterns targeting this plugin's endpoints can provide an additional layer of defense. Regularly updating all WordPress plugins and themes and subscribing to vulnerability notifications from trusted sources is recommended to ensure timely patching once available.
