CVE-2025-62896
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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in digitaldonkey Multilang Contact Form multilang-contact-form allows Stored XSS.This issue affects Multilang Contact Form: from n/a through <= 1.5.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in the Multilang Contact Form plugin allows unauthenticated attackers to trick authenticated administrators into submitting malicious requests that inject stored XSS payloads into the contact form configuration. When other users view the affected form, the injected JavaScript executes in their browsers.

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.
-
Verify Multilang Contact Form plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Multilang Contact Form' in the list. Note whether it is activated.Affected if The plugin is installed and activated in the WordPress environment
-
Inspect admin form submission code for nonce verificationAccess the plugin files via FTP or file manager. Locate the PHP file that handles form configuration submissions (typically in the admin folder). Search for wp_verify_nonce, check_admin_referer, or nonce verification calls within the form handler function.Affected if No nonce verification (wp_verify_nonce or check_admin_referer) is found in the form submission handler, indicating CSRF protection is missing
-
Check form configuration input handling for sanitizationIn the same plugin file that saves form settings, locate where POST/GET parameters are processed. Look for sanitization functions like sanitize_text_field, esc_attr, or wp_strip_all_tags applied to user inputs before saving to database.Affected if User inputs from form submissions are saved to the database without sanitization functions, allowing malicious script injection
-
Examine form output for output encodingLocate the plugin file that renders the contact form frontend. Search for output functions that display saved configuration values (e.g., echo, print). Verify that esc_html, esc_attr, or similar encoding functions are used when outputting stored configuration values.Affected if Stored configuration values are output on the frontend without encoding functions, allowing stored XSS to execute when users view the form
-
Manually test for stored XSS injectionAs an administrator, access the Multilang Contact Form settings page. In a configuration field (such as form title, message field, or label), inject a test payload like <script>alert('XSS')</script> or <img src=x onerror=alert('XSS')>. Save the settings, then view the form as a regular user would see it.Affected if The injected script executes in the browser when viewing the form, confirming both the stored XSS and the lack of output encoding
A user is affected if the Multilang Contact Form plugin is active AND admin form submissions lack nonce verification AND stored configuration values are rendered without output encoding, allowing injected scripts to execute.

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 dataImplement anti-CSRF tokens (nonces) on all form submissions and admin actions, and apply proper input sanitization and output encoding to prevent stored XSS. Update to a patched version when released.
