CVE-2026-0681: Extended Random Number Generator <= 1.1 - Authenticated (Administrator+) Stored Cross-Site Scripting via Settings

The Extended Random Number Generator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin settings in all versions up to, and including, 1.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Security readout for executives and security teams

Plain-English summary

CVE-2026-0681 affects the WordPress Extended Random Number Generator plugin through version 1.1. A logged-in administrator could save script content in plugin settings that later runs in a browser. Business urgency is limited because attacker privileges must already be high, and the issue only applies to multisite installs or sites where unfiltered_html is disabled.

Executive priority

Treat as a targeted cleanup item, not an emergency. Prioritize sites with many delegated administrators, multisite environments, or weak admin account controls. Remediate during the next plugin maintenance cycle unless suspicious admin activity is found.

Technical view

This is a stored cross-site scripting issue, CWE-79, caused by insufficient input sanitization and output escaping in plugin settings. The CVSS 3.1 score is 4.4, with high privileges and high attack complexity. Scope is changed, with low confidentiality and integrity impact and no availability impact. Sources identify versions up to and including 1.1.

Likely exposure

Exposure is likely limited to WordPress sites running Extended Random Number Generator <= 1.1, specifically multisite deployments or installations where unfiltered_html is disabled.

Exploitation context

No source in the bundle reports active exploitation, and the CVE is not listed as KEV. Abuse requires authenticated administrator-level access, reducing likelihood but still relevant for compromised admin accounts or delegated site administrators.

Researcher notes

The source data names versions through 1.1, but the affected-version metadata appears sparse. Validate against the WordPress plugin repository and Wordfence entry before broad conclusions. Do not assume a patch exists from the provided sources.

Mitigation direction

  • Inventory WordPress sites for the Extended Random Number Generator plugin.
  • Identify plugin versions up to and including 1.1.
  • Review vendor and WordPress plugin guidance for an official fix or replacement.
  • Restrict administrator access to trusted users only.
  • Remove or disable the plugin where it is not needed.

Validation and detection

  • Confirm whether WordPress multisite is enabled.
  • Confirm whether unfiltered_html is disabled on affected sites.
  • Review plugin settings for unexpected saved script content.
  • Check administrative account activity around plugin settings changes.
  • Compare installed plugin code and version with official WordPress plugin sources.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
