CVE-2025-30823 Overview
CVE-2025-30823 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Boone Gorges Anthologize plugin for WordPress. The flaw exists in all versions of Anthologize up to and including 0.8.2. An attacker can craft a malicious web page that triggers unwanted state-changing actions in the plugin when an authenticated WordPress user visits it. Successful exploitation requires user interaction, such as clicking a crafted link while logged into the target site. The issue is tracked under CWE-352: Cross-Site Request Forgery.
Critical Impact
An authenticated WordPress user can be tricked into performing unintended plugin actions, resulting in limited integrity impact on the affected site.
Affected Products
- Boone Gorges Anthologize plugin for WordPress
- All versions from n/a through 0.8.2
- WordPress sites with the vulnerable plugin installed and activated

Technical Details for CVE-2025-30823
Vulnerability Analysis
The Anthologize plugin fails to validate the origin of state-changing HTTP requests. WordPress plugins typically defend against CSRF using nonces generated by wp_create_nonce() and verified with check_admin_referer() or wp_verify_nonce(). In the affected versions of Anthologize, one or more request handlers process actions without this verification, allowing forged requests to succeed.
An attacker exploits this by luring an authenticated administrator or privileged user to a malicious page. The page issues a hidden request, using an auto-submitting form or embedded resource, to a vulnerable endpoint on the target WordPress site. The browser attaches the user's session cookies, and the plugin processes the request as legitimate.
The scope is limited to actions the victim is authorized to perform. Confidentiality and availability are not directly affected, but integrity of plugin-managed data can be modified without the user's consent.
Root Cause
The root cause is missing or improper CSRF token validation on request handlers within the Anthologize plugin. Without a nonce check tied to the user session, the plugin cannot distinguish requests initiated by the legitimate user from those forged by a third-party site.
Attack Vector
Exploitation occurs over the network and requires user interaction. The attacker hosts a malicious page or delivers a crafted link through phishing. When the authenticated victim opens the resource, the browser submits the forged request to the WordPress site. No credentials or elevated privileges are required on the attacker's side. See the Patchstack advisory for additional context.
Detection Methods for CVE-2025-30823
Indicators of Compromise
- Unexpected changes to Anthologize plugin settings or content generated outside normal administrator workflows.
- WordPress access log entries showing POST requests to Anthologize endpoints with Referer headers pointing to external, untrusted domains.
- Administrator sessions submitting plugin actions immediately after visiting unfamiliar external URLs.
Detection Strategies
- Review web server access logs for requests to Anthologize administrative endpoints with missing or foreign Referer and Origin headers.
- Correlate WordPress audit logs with browsing activity to identify plugin state changes that lack a matching admin UI interaction.
- Deploy a web application firewall rule that flags POST requests to plugin endpoints without a valid WordPress nonce parameter.
Monitoring Recommendations
- Enable a WordPress activity logging plugin to track configuration and content changes made through Anthologize.
- Alert on privileged user sessions that generate plugin actions from non-administrative referrers.
- Monitor outbound phishing indicators and inbound traffic patterns targeting /wp-admin/ paths tied to Anthologize.
How to Mitigate CVE-2025-30823
Immediate Actions Required
- Deactivate the Anthologize plugin until a patched version is available, since the vendor has not published a fix beyond version 0.8.2.
- Restrict administrative access to trusted networks and require reauthentication for sensitive operations.
- Educate administrators to avoid clicking untrusted links while logged into WordPress and to use a separate browser profile for site administration.
Patch Information
No vendor patch is currently referenced for Anthologize versions after 0.8.2. Track the Patchstack advisory for updates and consider replacing the plugin if the maintainer does not publish a fix.
Workarounds
- Remove the Anthologize plugin from production WordPress sites and use an alternative export tool.
- Enforce SameSite cookie attributes on WordPress authentication cookies to reduce cross-site request delivery.
- Deploy a WAF ruleset that requires the presence of a valid _wpnonce parameter on state-changing requests to plugin endpoints.
- Limit administrator sessions with short cookie lifetimes and mandatory two-factor authentication to reduce the exposure window.
