CVE-2024-49306 Overview
CVE-2024-49306 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the WP Content Copy Protection & No Right Click WordPress plugin developed by wp-buy. The flaw exists in all versions up to and including 3.5.9 and is tracked under [CWE-352]. An attacker who tricks an authenticated administrator into visiting a crafted page can force state-changing requests against the target WordPress site. Successful exploitation can compromise plugin configuration and lead to integrity, confidentiality, and availability impact on the affected installation.
Critical Impact
Attackers can leverage an authenticated administrator's session to perform unauthorized configuration changes on WordPress sites running the vulnerable plugin, potentially enabling further site compromise.
Affected Products
- wp-buy WP Content Copy Protection & No Right Click plugin for WordPress
- All versions from initial release through 3.5.9
- WordPress sites with the wp-content-copy-protector plugin installed and active

Technical Details for CVE-2024-49306
Vulnerability Analysis
The vulnerability stems from missing or improperly implemented anti-CSRF protections in plugin request handlers. WordPress provides a nonce mechanism through functions such as wp_nonce_field() and check_admin_referer() to validate the origin of administrative requests. When a plugin omits these checks, request handlers accept any properly formatted HTTP request regardless of origin.
An attacker hosting a malicious page can embed forged requests that the victim's browser submits automatically using existing authentication cookies. Because the plugin processes the request as if the administrator initiated it, the attacker indirectly performs privileged actions. Refer to the Patchstack WordPress Vulnerability Advisory for additional technical context.
Root Cause
The root cause is the absence of nonce verification on state-changing endpoints in versions through 3.5.9. Without nonce validation, the plugin cannot distinguish between legitimate administrator actions and forged cross-origin requests, satisfying the conditions described by [CWE-352].
Attack Vector
The attack vector is network based and requires user interaction. An attacker must convince an authenticated WordPress administrator to load attacker-controlled content, typically through phishing or a malicious link. Upon load, the browser submits the forged request to the target site, triggering the vulnerable handler with administrator privileges.
No proof-of-concept exploit code is publicly available for this issue. See the Patchstack WordPress Vulnerability Advisory for vendor-provided details.
Detection Methods for CVE-2024-49306
Indicators of Compromise
- Unexpected modifications to WP Content Copy Protection & No Right Click plugin settings recorded in the WordPress database
- HTTP POST requests to plugin administrative endpoints originating from external Referer headers
- Administrator session activity correlating with visits to untrusted external pages
Detection Strategies
- Inspect web server access logs for requests to wp-admin plugin endpoints lacking valid Referer headers from the same origin
- Monitor WordPress audit logs for configuration changes to the wp-content-copy-protector plugin that do not match scheduled administrator activity
- Review installed plugin versions across the estate and flag any instance of wp-content-copy-protector at version 3.5.9 or earlier
Monitoring Recommendations
- Enable a WordPress activity logging plugin to capture administrator-initiated setting changes with timestamps and source IP addresses
- Forward web server and WordPress logs to a centralized log analytics platform for correlation against phishing and browsing telemetry
- Alert on administrator account actions that occur shortly after the account loads external, non-corporate URLs
How to Mitigate CVE-2024-49306
Immediate Actions Required
- Identify all WordPress sites running the WP Content Copy Protection & No Right Click plugin at version 3.5.9 or earlier
- Apply the vendor-supplied patched release as soon as it becomes available through the WordPress plugin repository
- Require administrators to log out of WordPress sessions before browsing untrusted content and enforce short session lifetimes
Patch Information
Consult the Patchstack WordPress Vulnerability Advisory for the latest fixed version information. Upgrade the plugin through the WordPress administrative dashboard or via WP-CLI once a patched release is published by wp-buy.
Workarounds
- Deactivate and remove the wp-content-copy-protector plugin until a fixed version is installed
- Deploy a Web Application Firewall (WAF) rule that validates the Origin and Referer headers on requests to plugin administrative endpoints
- Restrict access to /wp-admin/ paths by IP allowlist for administrative users where feasible
# Configuration example: identify and remove the vulnerable plugin using WP-CLI
wp plugin list --name=wp-content-copy-protector --field=version
wp plugin deactivate wp-content-copy-protector
wp plugin uninstall wp-content-copy-protector
