CVE-2025-32266 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the WordPress plugin '404 Image Redirection (Replace Broken Images)' developed by wp-buy. This plugin is designed to replace broken images on websites by redirecting them to a specified image, improving user experience on sites with missing image resources. The vulnerability affects all versions up to and including 1.4. CSRF vulnerabilities occur when an attacker tricks an authenticated user, typically an administrator, into submitting unwanted requests to a web application without their knowledge. In this case, an attacker can craft a malicious web page or link that, when visited by an authenticated WordPress admin, causes the plugin to perform unauthorized actions such as changing redirection settings or other plugin configurations. The vulnerability does not require the attacker to have direct access to the victim's credentials but relies on the victim being logged in with sufficient privileges. No CVSS score has been assigned yet, and no public exploits have been reported. The lack of patch links suggests that a fix may not be available at the time of publication. The vulnerability primarily threatens the integrity of the plugin's configuration and could indirectly affect site availability if misused to disrupt image redirection functionality. Since the plugin is specific to WordPress sites, the scope is limited to websites using this plugin, which is a niche subset of the WordPress ecosystem. The vulnerability was published on April 4, 2025, by Patchstack, a known vulnerability aggregator for WordPress plugins.

The primary impact of this CSRF vulnerability is unauthorized modification of the plugin's settings by an attacker leveraging an authenticated administrator's session. This can lead to malicious redirection of broken images, potentially defacing websites, injecting malicious content, or disrupting user experience. While the vulnerability does not directly lead to data leakage or remote code execution, it compromises the integrity of the affected sites and can damage reputation. Organizations relying on this plugin for image management may experience degraded site functionality or user trust issues. Since exploitation requires an authenticated administrator, the risk is mitigated somewhat by the need for privileged access, but social engineering or phishing attacks could facilitate exploitation. The absence of known exploits in the wild reduces immediate risk but does not eliminate it, especially as attackers may develop exploits post-disclosure. The impact is more significant for high-traffic websites, e-commerce platforms, or sites where image presentation is critical. Additionally, if attackers combine this vulnerability with other weaknesses, it could be part of a larger attack chain. Overall, the impact is moderate but should not be ignored.

To mitigate this vulnerability, organizations should first verify if they are using the '404 Image Redirection (Replace Broken Images)' plugin version 1.4 or earlier. If so, they should monitor the vendor or Patchstack for an official patch and apply it immediately upon release. In the absence of a patch, administrators can implement manual CSRF protections by adding nonce verification to the plugin's form submissions and AJAX requests, ensuring that requests originate from legitimate sources. Restricting administrative access to trusted IP addresses and enforcing multi-factor authentication (MFA) for WordPress admin accounts can reduce the risk of exploitation. Additionally, educating administrators about the risks of visiting untrusted websites while logged in to WordPress can help prevent CSRF attacks. Employing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns may provide temporary protection. Regularly auditing plugin usage and minimizing the number of installed plugins reduces the attack surface. Finally, consider alternative plugins with better security track records if timely patching is not feasible.
