CVE-2024-11892
CVE-2024-11892: Stored Cross-Site Scripting (XSS) vulnerability in the WordPress Accordion Slider Lite plugin. This flaw allows authenticated users with contributor or higher privileges to inject malicious web scripts into pages. This vulnerability, present in versions up to 1.5.1, stems from inadequate input sanitization. The attack is executed through the 'accordion_slider' shortcode. While the CVSS score is 6.4, the SOCRadar Vulnerability Risk Score (SVRS) is 34, indicating a lower level of immediate threat compared to critical vulnerabilities. However, the presence of a CWE-79 classification emphasizes the inherent risk of XSS vulnerabilities which can lead to account takeover or malware distribution. Mitigation remains essential despite the SVRS score.
Description
CVE-2024-11892 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Accordion Slider Lite plugin for WordPress. This vulnerability arises due to insufficient input sanitization and output escaping on user-supplied attributes within the plugin's accordion_slider shortcode. The vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These scripts execute whenever a user accesses an injected page.
The SOCRadar Vulnerability Risk Score (SVRS) for this CVE is 34. While this score is below the critical threshold of 80, the fact that this vulnerability is "In The Wild" suggests it is actively exploited by hackers. This should be considered a significant risk for users of the Accordion Slider Lite plugin, requiring immediate attention and mitigation.
Key Insights

- Impact: Successful exploitation can lead to website defacement, data theft, account takeover, and other malicious activities.
- Accessibility: The vulnerability is exploitable by authenticated attackers with contributor-level access or higher, meaning a relatively low barrier for exploitation exists.
