Unknown Unknown - Not Provided

Missing Authorization in Easy Replace Image Plugin Allows Image Replacement

Publication date: 2026-01-28

Last updated on: 2026-04-08

Assigner: Wordfence

Description

The Easy Replace Image plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.5.2. This is due to missing capability checks on the `image_replacement_from_url` function that is hooked to the `eri_from_url` AJAX action. This makes it possible for authenticated attackers, with Contributor-level access and above, to replace arbitrary image attachments on the site with images from external URLs, potentially enabling site defacement, phishing attacks, or content manipulation.

Attack-Flow Graph

Executive Summary

The Easy Replace Image plugin for WordPress has a vulnerability due to missing authorization checks in the function that handles image replacement from URLs. This allows authenticated users with Contributor-level access or higher to replace any image attachments on the site with images from external URLs without proper permission checks.

Impact Analysis

This vulnerability can allow attackers with Contributor-level access to replace images on the site with arbitrary external images, potentially leading to site defacement, phishing attacks, or manipulation of site content.

Mitigation Strategies

To mitigate this vulnerability, immediately update the Easy Replace Image plugin to a version later than 3.5.2 where the missing authorization checks are fixed. Additionally, restrict Contributor-level access and above to trusted users only, and monitor for unauthorized image replacements. If an update is not available, consider disabling the plugin or the 'eri_from_url' AJAX action to prevent exploitation.
