Description
The EchBay Admin Security plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the '_ebnonce' parameter in all versions up to, and including, 1.3.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

AI Analysis

Impact

The EchBay Admin Security plugin for WordPress contains a reflected Cross‑Site Scripting flaw (CWE‑79) triggered by the '_ebnonce' query parameter. The plugin does not properly sanitize or escape this input before rendering it in page content, allowing an unauthenticated attacker to inject arbitrary JavaScript that will execute when a victim opens a crafted link.

Affected Systems

WordPress sites that have the EchBay Admin Security plugin version 1.3.0 or earlier, distributed by itvn9online.

Risk and Exploitability

The CVSS score of 6.1 indicates moderate severity, while an EPSS value of less than 1% suggests a low likelihood of exploitation at this time. The vulnerability is not listed in the CISA KEV catalog. Attacks require social engineering to get a user to click a malicious link, and no authenticated access is necessary. When executed, the injected scripts run with the victim’s browser privileges, potentially allowing unintended client‑side actions.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade EchBay Admin Security to the latest version (≥1.3.1) or remove the plugin entirely if it is no longer required.
  • Ensure that any user‑supplied data is properly sanitized and escaped before being output to the browser, particularly query string parameters.
  • Implement a web‑application firewall rule that blocks or neutralizes script payloads in the '_ebnonce' parameter, or otherwise filters malicious JavaScript content from incoming requests.
