CVE-2025-49430: Ultimate Video Player SSRF Vulnerability

CVE-2025-49430 is a server-side request forgery vulnerability in FWDesign Ultimate Video Player (versions up to 10.1) that enables attackers to manipulate server requests. This article covers technical details, impact, and mitigation.

Updated: May 15, 2026

CVE-2025-49430 Overview

CVE-2025-49430 is a Server-Side Request Forgery (SSRF) vulnerability [CWE-918] affecting the FWDesign Ultimate Video Player (fwduvp) WordPress plugin. The flaw exists in all versions up to and including 10.1. An unauthenticated attacker can coerce the vulnerable WordPress server into issuing arbitrary HTTP requests to attacker-chosen destinations. This enables interaction with internal services, metadata endpoints, and other resources that should be inaccessible from the public internet.

Critical Impact

Unauthenticated attackers can force the WordPress server to send arbitrary HTTP requests, exposing internal network resources and cloud metadata endpoints.

Affected Products

  • FWDesign Ultimate Video Player (fwduvp) WordPress plugin
  • All versions from n/a through 10.1
  • WordPress sites with the plugin installed and active

Discovery Timeline

  • 2025-09-09 - CVE-2025-49430 published to NVD
  • 2026-04-23 - Last updated in NVD database

Technical Details for CVE-2025-49430

Vulnerability Analysis

The Ultimate Video Player plugin processes a user-supplied URL parameter without validating its destination. The server-side handler then performs an outbound request using that URL. Because the plugin neither restricts target hosts nor validates against an allowlist, attackers can supply URLs pointing to internal IP ranges, loopback addresses, or cloud metadata services.

The vulnerability scores 7.2 with a changed scope, reflecting that exploitation impacts resources beyond the vulnerable component itself. Confidentiality and integrity impacts are limited to low because the attacker controls only the outbound request and reads or proxies the response.

Root Cause

The root cause is missing validation of the destination URL before the plugin issues server-side HTTP requests. The plugin trusts attacker-controlled input as a request target. Schemes such as http://, https://, file://, or gopher:// may be processed depending on the underlying HTTP client. No authentication is required to reach the vulnerable endpoint.

Attack Vector

An attacker sends a crafted request to the plugin endpoint containing a malicious URL parameter. The WordPress server then fetches that URL using its own network context. Typical SSRF targets include http://169.254.169.254/ for AWS instance metadata, http://127.0.0.1/ for local admin services, and internal RFC1918 ranges hosting databases or management consoles. The attacker can use the response to enumerate internal services or exfiltrate cloud credentials.

No public proof-of-concept exploit is currently available. Refer to the Patchstack SSRF Vulnerability Advisory for additional technical context.

Detection Methods for CVE-2025-49430

Indicators of Compromise

  • Outbound HTTP requests from the WordPress server to internal IP ranges (RFC1918), 127.0.0.1, or 169.254.169.254
  • Unusual User-Agent strings originating from the PHP process that match WordPress HTTP client signatures
  • Web access logs showing repeated requests to fwduvp plugin endpoints with URL-like parameters
  • Outbound connections from the web server to cloud metadata endpoints not associated with normal application behavior

Detection Strategies

  • Inspect web server access logs for requests targeting /wp-content/plugins/fwduvp/ containing fully qualified URLs in query strings or POST bodies
  • Correlate inbound HTTP requests with subsequent outbound connections from the web server within short time windows
  • Deploy egress monitoring to flag any web server connections to link-local, loopback, or private address space

Monitoring Recommendations

  • Enable WordPress audit logging to capture plugin endpoint access patterns
  • Forward web server and firewall egress logs to a SIEM for correlation analysis
  • Alert on PHP-originated network requests to cloud metadata IP addresses such as 169.254.169.254 and fd00:ec2::254

How to Mitigate CVE-2025-49430

Immediate Actions Required

  • Identify all WordPress instances running the FWDesign Ultimate Video Player plugin version 10.1 or earlier
  • Disable or remove the plugin until a patched version is confirmed installed
  • Restrict outbound network access from WordPress hosts to internal networks and cloud metadata endpoints
  • Review web server and application logs for prior exploitation attempts targeting plugin endpoints

Patch Information

At the time of this writing, the vendor advisory tracked by Patchstack indicates the vulnerability affects versions up to and including 10.1. Administrators should consult the Patchstack SSRF Vulnerability Advisory and the FWDesign vendor channel for fixed version availability and upgrade guidance.

Workarounds

  • Deploy a web application firewall (WAF) rule that blocks requests to fwduvp endpoints containing URL parameters referencing internal or metadata IP ranges
  • Configure egress firewall rules on WordPress hosts to deny outbound traffic to RFC1918, loopback, and link-local addresses where not operationally required
  • Enforce IMDSv2 on AWS instances hosting WordPress to mitigate credential theft via SSRF against the instance metadata service
  • Place the WordPress instance behind a reverse proxy that strips or validates outbound request destinations originating from plugin code
bash
# Example egress restriction using iptables to block metadata access
iptables -A OUTPUT -m owner --uid-owner www-data -d 169.254.169.254 -j DROP
iptables -A OUTPUT -m owner --uid-owner www-data -d 127.0.0.0/8 -j DROP
iptables -A OUTPUT -m owner --uid-owner www-data -d 10.0.0.0/8 -j DROP
iptables -A OUTPUT -m owner --uid-owner www-data -d 192.168.0.0/16 -j DROP
