Security readout for executives and security teams
Plain-English summary
CVE-2025-22558 is a stored cross-site scripting issue in the WordPress mcjh button shortcode plugin through version 1.6.4. A lower-privileged authenticated user may be able to save unsafe content that later runs in another user's browser. Business risk is mainly site integrity, account trust, and visitor or administrator session exposure.
Executive priority
Treat as a moderate WordPress application risk. Prioritize sites where the plugin is present, content editing is delegated, or administrator sessions may view user-supplied content.
Technical view
The CVE describes CWE-79 improper input neutralization during web page generation in mcjh-button-shortcode. CVSS 3.1 is 6.5 with network attack vector, low complexity, low privileges required, user interaction required, and changed scope. The source bundle does not name the vulnerable parameter, a proof of concept, or a fixed version.
Likely exposure
Exposure appears limited to WordPress sites with mcjh button shortcode installed and enabled at version 1.6.4 or earlier, especially where non-admin users can create or edit shortcode-backed content.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not listed as KEV in the bundle. Exploitation would require an authenticated user with some content capability and a victim viewing affected stored content.
Researcher notes
Evidence is metadata-level. The bundle identifies stored XSS and CVSS details but does not provide root-cause code context, exploit maturity, affected shortcode fields, or confirmed remediation version. Avoid assuming broader product impact.
Mitigation direction
- Inventory WordPress sites for mcjh-button-shortcode installation and version.
- Disable or remove the plugin if it is unnecessary.
- Check vendor or Patchstack guidance for an official fixed version.
- Restrict content editing privileges to trusted users until remediated.
- Review WordPress roles that can publish or edit shortcode content.
Validation and detection
- Confirm whether mcjh-button-shortcode is installed and active.
- Record the installed version and compare it with the affected range through 1.6.4.
- Review users and roles allowed to edit pages, posts, or shortcode content.
- Inspect affected content areas for unexpected script-bearing markup.

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.
