AI Analysis
Technical Summary
The Premium Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) via the 'custom_svg' parameter. Authenticated users with contributor or higher privileges can inject arbitrary web scripts due to improper input neutralization during page generation. This vulnerability affects all versions up to 4.11.70. The CVSS 3.1 base score is 5.4 (medium severity), with network attack vector, low attack complexity, requiring privileges and user interaction, and impacts confidentiality and integrity with no availability impact. No vendor advisory or patch is currently available, and the plugin is not a cloud service.
Potential Impact
Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, which execute in the context of users visiting those pages. This can lead to unauthorized actions or data disclosure limited to the privileges of the affected users. The impact is limited to confidentiality and integrity with no direct availability impact. There are no known active exploits reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the 'custom_svg' parameter if possible. Monitor for updates from the vendor and apply official patches once released.
