CVE-2025-30634: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in IWEBIX WP Featured Content Slider
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in IWEBIX WP Featured Content Slider allows Stored XSS. This issue affects WP Featured Content Slider: from n/a through 2.6.
AI Analysis
Technical Summary
CVE-2025-30634 is a medium-severity vulnerability classified under CWE-79, which pertains to improper neutralization of input during web page generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the IWEBIX WP Featured Content Slider plugin for WordPress, specifically versions up to 2.6. The flaw allows an attacker to inject malicious scripts that are stored persistently within the plugin's data handling processes. When a victim loads a page containing the compromised slider, the malicious script executes in the context of the victim's browser. The CVSS 3.1 base score of 5.9 reflects a network attack vector (AV:N), low attack complexity (AC:L), but requiring high privileges (PR:H) and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability impacts, but the stored nature of the XSS can facilitate persistent attacks such as session hijacking, defacement, or distribution of malware. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability arises because the plugin fails to properly sanitize or encode user input before rendering it on web pages, allowing malicious JavaScript code to be embedded and executed in users' browsers.
Potential Impact
For European organizations using WordPress sites with the WP Featured Content Slider plugin, this vulnerability poses a risk of persistent cross-site scripting attacks. Attackers could exploit this to steal session cookies, perform actions on behalf of authenticated users, or redirect users to malicious sites. This can lead to data breaches, reputational damage, and potential regulatory non-compliance under GDPR if personal data is compromised. Since the vulnerability requires high privileges and user interaction, it is more likely to be exploited by insiders or through social engineering targeting administrators or editors with access to the plugin's content management features. The impact on availability is low but could include defacement or disruption of website functionality. Given the widespread use of WordPress in Europe, especially among SMEs and public sector websites, the vulnerability could affect a broad range of organizations if the plugin is installed and not updated promptly.
Mitigation Recommendations
Organizations should first identify if they use the IWEBIX WP Featured Content Slider plugin on their WordPress sites. If present, they should monitor for official patches or updates from IWEBIX and apply them immediately once available. Until a patch is released, administrators should restrict plugin access to trusted users only and implement strict input validation and sanitization controls at the application level where possible. Employing Web Application Firewalls (WAFs) with rules to detect and block XSS payloads targeting the plugin's endpoints can provide interim protection. Additionally, organizations should educate administrators and content editors about the risks of social engineering and the importance of cautious input handling. Regular security audits and scanning for XSS vulnerabilities in web applications can help detect exploitation attempts early. Finally, enforcing Content Security Policy (CSP) headers can reduce the impact of successful XSS by restricting script execution sources.
