CVE-2026-8048
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe My Email Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'subject' shortcode attribute in the 'my-email' shortcode in all versions up to, and including, 0.91 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe My Email Shortcode WordPress plugin fails to sanitize the 'subject' shortcode attribute input and escape it when outputting, allowing stored XSS injection. Attackers with Contributor-level access can embed malicious JavaScript in the subject parameter that executes whenever page visitors access the injected content.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'My Email Shortcode' in the list. Note the installed version number displayed alongside the plugin name.Affected if The plugin appears in the installed plugins list with any version number.
-
Check if shortcode is in useSearch your WordPress database or content pages for the presence of [my_email] or [my_email_subject] shortcode tags. This can be done via phpMyAdmin by querying wp_posts for post_content containing 'my_email', or by using a plugin to scan content.Affected if Any page, post, or custom post type content contains the my_email shortcode with a subject attribute.
-
Inspect shortcode subject values for scriptsExamine the subject parameter in any my_email shortcode found in content. Look for unusual patterns such as <script> tags, javascript: URLs, event handlers like onload/onerror, or encoded characters that may resolve to malicious code.Affected if Any subject attribute contains JavaScript code, script tags, or suspicious event handlers.
-
Verify contributor-level users existIn WordPress admin, go to Users and review the role assigned to each user. Contributors have edit capability on their own posts but cannot publish.Affected if There are user accounts with Contributor role or other roles that can create content with shortcodes.
You are affected if the My Email Shortcode plugin is installed and any content contains the shortcode with a subject attribute that includes unsanitized or encoded script content.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the plugin to a patched version once available; in the interim, restrict shortcode usage permissions or disable the plugin until fixed, and audit existing pages for injected shortcode payloads.
