CVE-2025-47483: Easy Replace Image SSRF Vulnerability

CVE-2025-47483 Overview

CVE-2025-47483 is a Server-Side Request Forgery (SSRF) vulnerability [CWE-918] in the Iulia Cazan Easy Replace Image plugin for WordPress. The flaw affects all versions from n/a through 3.5.0. An authenticated attacker with low privileges can coerce the vulnerable WordPress server into issuing HTTP requests to arbitrary destinations. Successful exploitation can expose internal services or metadata endpoints that are not reachable from the public internet.

Critical Impact
An authenticated user can abuse the plugin to make the WordPress host issue attacker-controlled outbound requests, enabling internal network reconnaissance and limited data exposure.

Affected Products

Iulia Cazan Easy Replace Image plugin for WordPress
All versions up to and including 3.5.0
WordPress sites where the plugin is installed and active

Technical Details for CVE-2025-47483

Vulnerability Analysis

The Easy Replace Image plugin accepts a user-supplied URL and instructs the WordPress server to fetch the resource at that URL. The plugin does not adequately validate or restrict the destination of that request. As a result, an authenticated attacker can supply URLs pointing to internal-only endpoints, such as 127.0.0.1, RFC1918 ranges, or cloud metadata services like http://169.254.169.254/.

The scope-change indicator in the vulnerability metadata reflects that the request originates from the WordPress server itself. This allows the attacker to reach services that trust local or internal traffic. Confidentiality and integrity impacts are limited but present, because the response body can be reflected back or written to a media object controlled by the requester.

Root Cause

The root cause is missing or insufficient validation of user-controlled URL input before the plugin invokes a server-side HTTP fetch. There is no allowlist of permitted hosts, no filtering of private address ranges, and no scheme restriction to prevent non-HTTP protocols supported by the underlying request library. This class of flaw is tracked as CWE-918: Server-Side Request Forgery.

Attack Vector

Exploitation requires network access to the WordPress site and low-privileged authenticated access. The attacker submits a crafted request to the plugin's image replacement endpoint with a URL pointing to an internal target. The WordPress server performs the outbound request and may return content or side effects to the attacker. High attack complexity indicates that reliable exploitation depends on environmental factors such as the presence of reachable internal services. Refer to the Patchstack SSRF Vulnerability Advisory for additional technical context.

Detection Methods for CVE-2025-47483

Indicators of Compromise

Outbound HTTP requests from the WordPress PHP worker to internal IP ranges (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).
Requests from the WordPress host to cloud metadata endpoints such as 169.254.169.254.
Unexpected entries in the WordPress media library referencing non-image internal URLs.
Access log entries showing authenticated calls to Easy Replace Image admin-ajax or REST endpoints with URL parameters.

Detection Strategies

Inspect web server access logs for POST requests to plugin endpoints containing url= parameters targeting private or link-local addresses.
Correlate outbound connection telemetry from the WordPress host against expected upstream destinations.
Alert on any HTTP client activity originating from PHP-FPM or Apache worker processes toward the instance metadata service.

Monitoring Recommendations

Enable egress logging on the WordPress host and forward logs to a centralized analytics platform.
Monitor authentication events for low-privileged accounts performing plugin actions outside normal editorial workflows.
Track plugin version inventory across WordPress installations to identify hosts running Easy Replace Image at or below 3.5.0.

How to Mitigate CVE-2025-47483

Immediate Actions Required

Identify all WordPress sites with the Easy Replace Image plugin installed and confirm the installed version.
Deactivate the plugin on any site running version 3.5.0 or earlier until a patched release is applied.
Review recent media library uploads and plugin activity logs for evidence of abuse.
Restrict WordPress outbound network access to only the destinations required for site operation.

Patch Information

At the time of publication, the advisory lists affected versions up to and including 3.5.0 with no fixed version confirmed in the referenced sources. Monitor the Patchstack advisory and the plugin's WordPress.org page for a patched release, and update as soon as a fixed version is available.

Workarounds

Block egress traffic from the WordPress host to private address ranges and cloud metadata endpoints at the firewall or security group level.
Enforce least-privilege on WordPress user accounts and remove unnecessary contributor or author roles.
Place a web application firewall in front of WordPress and filter requests containing URL parameters that reference internal IPs or non-HTTP schemes.
Run WordPress under a container or network namespace that has no route to sensitive internal services.
