CVE-2024-13743: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in wonderplugin Wonder Video Embed
The Wonder Video Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wonderplugin_video shortcode in all versions up to, and including, 2.2 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2024-13743 is a stored cross-site scripting vulnerability in the Wonder Video Embed WordPress plugin (up to version 2.2). The issue is due to improper neutralization of user-supplied input in the wonderplugin_video shortcode, which fails to adequately sanitize and escape attributes. Authenticated users with at least contributor privileges can inject arbitrary JavaScript that executes in the context of any user viewing the affected page. This vulnerability can lead to limited confidentiality and integrity impacts but does not affect availability. The CVSS 3.1 base score is 6.4 (medium), reflecting network attack vector, low attack complexity, and required privileges.
Potential Impact
An attacker with contributor-level or higher access can inject persistent malicious scripts into pages using the vulnerable shortcode. These scripts execute in the browsers of users who visit the injected pages, potentially leading to information disclosure or manipulation of content within the affected site context. The vulnerability does not impact system availability. There are no known active exploits reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Wonder Video Embed plugin if possible. Monitor for updates from the vendor regarding patches or official mitigations.
