Security readout for executives and security teams

Plain-English summary

CVE-2026-25341 is a stored cross-site scripting issue in the WordPress RSFirewall! plugin up to version 1.1.45. An attacker could cause malicious script to be stored and later executed in a user’s browser when viewed. The record does not show CISA KEV listing or confirmed active exploitation.

Executive priority

Treat as high priority for WordPress environments using RSFirewall!, especially public-facing or business-critical sites. The issue can affect user trust and administrative sessions, but available evidence does not support emergency action for organizations that do not run this plugin.

Technical view

The CVE describes CWE-79 improper neutralization during web page generation in RSJoomla! RSFirewall! for WordPress, affecting versions through 1.1.45. CVSS 3.1 is 7.1: network exploitable, low complexity, no privileges, user interaction required, changed scope, and low confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to WordPress sites running the RSJoomla! RSFirewall! plugin at version 1.1.45 or earlier. The provided data does not identify affected Joomla products, hosted services, or other RSJoomla! components.

Exploitation context

This is stored XSS, so risk depends on whether an attacker can place malicious content into a location later viewed by an administrator or user. The CVSS vector indicates user interaction is required. No provided source confirms exploitation in the wild.

Researcher notes

The source bundle contains a CVE record and Patchstack database reference, but no detailed vulnerable parameter, proof of concept, fixed version, or vendor advisory text. The affected metadata appears inconsistent, while the description clearly states RSFirewall! through 1.1.45.

Mitigation direction

  • Inventory WordPress sites for the RSFirewall! plugin and record installed versions.
  • Prioritize sites running RSFirewall! version 1.1.45 or earlier.
  • Check RSJoomla!, WordPress plugin, and Patchstack guidance for a fixed version or workaround.
  • Restrict administrative access and review untrusted content paths until vendor guidance is confirmed.
  • Apply an available vendor-supported update once identified.

Validation and detection

  • Confirm whether RSFirewall! is installed on each WordPress instance.
  • Compare installed plugin versions against the affected range through 1.1.45.
  • Review web application logs for unusual stored-content changes or suspicious administrator page views.
  • Verify any remediation against official vendor or Patchstack information.
