Cross-Site Request Forgery in Bulk SEO Image WordPress Plugin

Publication date: 2026-06-24

Last updated on: 2026-06-24

Assigner: Wordfence

Description
The Bulk SEO Image plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.1. This is due to missing or incorrect nonce validation on the plugin's settings page handler BulkSeoImage(), which dispatches to launchbulk() / BulkSeoImageGo() whenever the request contains $_POST['bulkseoimage']. No wp_nonce_field() is emitted in the form and no check_admin_referer()/wp_verify_nonce() is performed before bulk-overwriting the _wp_attachment_image_alt post meta for every image attached to every published post and/or page. This makes it possible for unauthenticated attackers to bulk-overwrite image ALT-text metadata across the site via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Executive Summary

The Bulk SEO Image plugin for WordPress has a Cross-Site Request Forgery (CSRF) vulnerability in versions up to and including 1.1. This happens because the plugin's settings page handler does not properly validate nonces, which are security tokens meant to verify the authenticity of requests.

Specifically, the plugin does not emit a nonce field in its form and does not check the nonce before bulk-overwriting the ALT-text metadata of images attached to published posts or pages. This allows an attacker to trick a site administrator into performing an unwanted action, such as clicking a malicious link, which then causes the attacker to overwrite image ALT-text metadata across the site.

Impact Analysis

This vulnerability allows an unauthenticated attacker to bulk-overwrite the ALT-text metadata of images on a WordPress site by tricking an administrator into clicking a malicious link.

While it does not affect confidentiality or availability, it impacts the integrity of the site's image metadata, potentially leading to misinformation or SEO manipulation.

Mitigation Strategies

To mitigate this vulnerability, you should update the Bulk SEO Image plugin to a version later than 1.1 where the nonce validation issue is fixed.

Additionally, ensure that any forms handling sensitive actions implement proper nonce fields (wp_nonce_field()) and verify nonces (check_admin_referer() or wp_verify_nonce()) to prevent Cross-Site Request Forgery attacks.

Until an update is applied, restrict access to the plugin's settings page to trusted administrators only and avoid clicking on suspicious links that could trigger forged requests.
