CVE-2026-1755: Menu Icons by ThemeIsle <= 0.13.20 - Authenticated (Author+) Stored Cross-Site Scripting

The Menu Icons by ThemeIsle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘_wp_attachment_image_alt’ post meta in all versions up to, and including, 0.13.20 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1755 affects the WordPress plugin Menu Icons by ThemeIsle through version 0.13.20. A logged-in user with Author-level access or higher could store malicious script in image alt metadata, causing it to run when affected pages are viewed. This is not marked as actively exploited in the provided sources.

Executive priority

Treat as a normal-priority web application remediation unless your site allows many authors or has recent account compromise concerns. The business risk is browser-based script execution against site users or administrators, not direct server takeover based on current evidence.

Technical view

The issue is stored cross-site scripting, CWE-79, caused by insufficient input sanitization and output escaping of the _wp_attachment_image_alt post meta. Wordfence rates it CVSS 6.4. The attack requires authenticated Author+ privileges and can impact confidentiality and integrity in the browser context of viewers.

Likely exposure

Exposure is likely limited to WordPress sites running Menu Icons by ThemeIsle version 0.13.20 or earlier, especially where Author-level accounts are numerous, shared, or weakly protected.

Exploitation context

This is a post-authentication stored XSS issue. It is most concerning if an Author account is compromised or if contributors are not fully trusted. No KEV listing or provided source indicates active exploitation.

Researcher notes

The public record points to _wp_attachment_image_alt handling and a referenced WordPress plugin changeset. Evidence supports authenticated stored XSS through version 0.13.20. The provided sources do not include exploit-in-the-wild confirmation or detailed vendor release notes naming a fixed version.

Mitigation direction

  • Identify sites using Menu Icons by ThemeIsle.
  • Check whether the plugin version is 0.13.20 or earlier.
  • Update to a vendor-recommended version newer than 0.13.20, if available.
  • If no update is available, follow ThemeIsle or WordPress.org plugin guidance.
  • Restrict Author-level access to trusted users only.
  • Review and secure WordPress accounts with elevated content permissions.

Validation and detection

  • Confirm installed Menu Icons by ThemeIsle versions across WordPress sites.
  • Review WordPress users with Author, Editor, Administrator, or equivalent privileges.
  • Inspect image alt metadata and menu-icon related content for unexpected scripts.
  • Verify the plugin has been updated according to vendor guidance.
  • Check WordPress security logs for suspicious Author-level content changes.
