Security readout for executives and security teams
Plain-English summary
CVE-2026-22349 is a medium-severity cross-site scripting issue in the WordPress Menu In Post plugin. A logged-in attacker could cause script execution in another user’s browser if that user interacts with affected content. This can support limited data theft, content changes, or session-impacting activity, depending on site configuration.
Executive priority
Treat this as a moderate WordPress hygiene issue. Prioritize public-facing sites, high-traffic sites, and sites with many non-admin contributors. It does not currently warrant emergency response based on the provided sources, but it should be addressed during the next vulnerability remediation cycle.
Technical view
The CVE describes DOM-based XSS from improper input neutralization in linux4me2 Menu In Post, package menu-in-post, affecting versions through <= 1.4.1. CVSS 3.1 is 6.5: network attack vector, low complexity, low privileges required, user interaction required, changed scope, and low C/I/A impact.
Likely exposure
Exposure is limited to WordPress sites with the Menu In Post plugin installed, especially versions <= 1.4.1. The source bundle has inconsistent affected-version metadata, so teams should verify installed versions directly rather than relying only on automated CPE matching.
Exploitation context
No active exploitation is indicated in the provided sources, and the CVE is not listed as KEV. Exploitation requires some privileges and user interaction, reducing urgency versus unauthenticated bugs, but XSS in WordPress can still matter on sites with many contributors or administrators.
Researcher notes
The public data identifies CWE-79 DOM-based XSS and CVSS 6.5. The source bundle references Patchstack and CVE records, but does not provide exploit details, a named fixed version, or confirmed exploitation. Version data is partly inconsistent, so manual validation is important.
Mitigation direction
- Inventory WordPress sites for the Menu In Post plugin.
- Check vendor, WordPress.org, or Patchstack guidance for a fixed version.
- Update the plugin if a vendor-supported fixed release is available.
- Disable or remove the plugin where it is unnecessary.
- Limit contributor and author access on affected WordPress sites.
- Monitor affected sites for suspicious content or administrator-session anomalies.
Validation and detection
- Confirm whether menu-in-post is installed on each WordPress site.
- Record the installed plugin version and compare against <= 1.4.1.
- Review user roles with access to create or edit affected content.
- Check security tooling for XSS findings tied to Menu In Post.
- Verify any remediation by confirming the plugin is updated, disabled, or removed.

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.
