CVE-2026-12402: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in xootix OTP Login & Register Woocommerce
The OTP Login & Register Woocommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'fb-config' Setting in all versions up to, and including, 2.7.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. On multisite installations where administrators do not hold the unfiltered_html capability, this vulnerability can be leveraged to target the network super administrator.

Technical Summary
CVE-2026-12402 is a stored cross-site scripting vulnerability in the OTP Login & Register Woocommerce WordPress plugin. The issue stems from insufficient sanitization and escaping of input in the 'fb-config' setting, permitting authenticated administrators to inject arbitrary scripts that execute when users visit the affected pages. On multisite setups, the vulnerability can be leveraged against the network super administrator under certain capability restrictions. The affected versions include all plugin versions from 0 up to and including 2.7.3.
Potential Impact
An authenticated attacker with administrator-level access or higher can inject malicious scripts into pages via the vulnerable 'fb-config' setting. This can lead to script execution in the context of users visiting those pages, potentially compromising user data or session integrity. On multisite WordPress installations, the vulnerability can be exploited to target the network super administrator if administrators do not have the unfiltered_html capability. There is no indication of active exploitation in the wild.
Mitigation Recommendations
No official patch or fix has been confirmed for this vulnerability. Users should check the vendor's advisory or updates for remediation guidance. Until a fix is available, restrict administrator access to trusted users only and consider disabling or removing the plugin if possible. Monitor for vendor updates regarding patches.
