Vulnerability in Smart Slider Plugin Affects Over 500,000 WordPress Sites
A Critical Vulnerability Affects Over 500,000 Websites
The Smart Slider 3 WordPress plugin has been found to have a serious vulnerability, identified as CVE-2026-3098. This flaw affects more than half a million websites and allows authenticated attackers to access sensitive files.
Risk Assessment:
- Data Theft: Attackers can gain access to the wp-config.php file, containing database credentials, keys, and salt data.
- Complete Website Takeover: With access to sensitive files, attackers can compromise the entire website.
The vulnerability arises from the lack of capability checks in the plugin’s AJAX export actions, specifically in the ‘actionExportAll’ function. This omission enables attackers to read and add arbitrary server files to the export archive.
It is crucial for website administrators to promptly apply the latest update to ensure their sites remain secure. While CVE-2026-3098 is currently not flagged as actively exploited, it is vital to maintain vigilance and regularly perform automated pentesting and security audits to protect against future threats.
