CVE-2026-42681
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 · uneditedImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in E2Pdf.Com e2pdf allows Reflected XSS. This issue affects e2pdf: from n/a through 1.32.14.
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 · moderate confidenceReflected XSS vulnerability in e2pdf WordPress plugin where user-supplied input is not properly sanitized before being reflected in the web page output, allowing attackers to inject malicious JavaScript through crafted URLs.

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 E2Pdf plugin is installedNavigate to WordPress admin > Plugins, or inspect the wp-content/plugins/e2pdf directory existenceAffected if The E2Pdf plugin appears in the list of active or installed plugins
-
Identify installed E2Pdf versionIn WordPress admin, go to Plugins > Installed Plugins and find the version number listed under E2Pdf; alternatively, open the main plugin file (e.g., e2pdf.php) and locate the 'Version' header in the plugin commentsAffected if A version number is displayed and can be compared to any officially documented vulnerable versions
-
Verify the plugin handles URL parametersExamine HTTP requests to pages using E2Pdf functionality; check if the plugin processes query string parameters, POST data, or form inputs that get reflected in the page outputAffected if URL parameters or form inputs are processed and displayed back in the response without clear sanitization indicators
-
Test for reflected content in responsesSubmit a harmless test string (e.g., <script>alert('test')</script> or a benign alternate) as a parameter in E2Pdf-enabled pages and inspect the HTML source of the response to see if the input is reflected verbatim or improperly encodedAffected if The submitted test string appears in the HTML output without proper encoding (e.g., appears as <script> rather than <script>)
-
Review server-side output handlingIf code access is available, inspect the E2Pdf PHP files for usage of WordPress sanitization functions (esc_html, esc_attr, sanitize_text_field) or lack thereof on user-supplied data before outputAffected if User input is output directly or through functions that do not provide output encoding
A user is affected if the E2Pdf plugin is installed, the installed version matches a vulnerable release, and user-supplied input is reflected in pages without proper sanitization or encoding.

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 dataApply proper input validation and output encoding/sanitization to all user-controlled inputs in the affected e2pdf pages to prevent script injection.
