CVE-2025-64368 Overview
CVE-2025-64368 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Mikado-Themes Bard WordPress theme (bardwp). The flaw exists in all versions up to and including 1.6. An attacker can craft a malicious web page that, when visited by an authenticated WordPress user, triggers unauthorized state-changing actions in the target site under the victim's session context. The weakness maps to CWE-352: Cross-Site Request Forgery.
Critical Impact
Attackers can trick authenticated WordPress administrators into performing unintended actions on the Bard theme, resulting in limited integrity and availability impact on the affected site.
Affected Products
- Qodeinteractive Bard WordPress theme (bardwp)
- All versions from initial release through 1.6
- WordPress sites using the Bard theme with authenticated admin sessions

Technical Details for CVE-2025-64368
Vulnerability Analysis
The Bard WordPress theme fails to implement adequate CSRF protection on one or more state-changing endpoints. WordPress provides a nonce mechanism (wp_nonce_field() and check_admin_referer()) intended to bind a request to a specific user session. When theme handlers omit or fail to validate these nonces, an external site can forge requests that the browser submits with the victim's authentication cookies.
Exploitation requires user interaction (UI:R), typically by luring an authenticated administrator to a malicious page. The scope remains unchanged, and the vulnerability affects integrity and availability rather than confidentiality. Additional details are available in the Patchstack WordPress Vulnerability database entry.
Root Cause
The root cause is missing or improper CSRF token validation on privileged theme actions. Without verifying a per-session nonce or checking the Origin/Referer header, the theme accepts any authenticated request regardless of its source. This is a classic instance of CWE-352.
Attack Vector
The attack is delivered over the network. An attacker hosts a page containing a hidden form or JavaScript-triggered request targeting the vulnerable Bard endpoint. When a logged-in WordPress user visits the page, the browser automatically attaches session cookies, and the forged request executes with the victim's privileges. No credentials or prior access are required on the attacker side.
No verified public exploit code or proof-of-concept is currently available. See the Patchstack advisory for coordinated disclosure details.
Detection Methods for CVE-2025-64368
Indicators of Compromise
- Unexpected changes to Bard theme options or configuration without a corresponding administrator login session.
- HTTP POST requests to Bard admin endpoints with Referer headers pointing to external, untrusted domains.
- Administrator account activity originating from unusual client contexts shortly after visiting third-party sites.
Detection Strategies
- Review WordPress audit logs for state-changing theme actions that lack a preceding legitimate admin navigation flow.
- Inspect web server access logs for POST requests to wp-admin endpoints where the Referer is off-site or missing.
- Correlate browser session activity with theme configuration change events to identify forged requests.
Monitoring Recommendations
- Enable a WordPress audit logging plugin to track administrative changes to theme settings and options.
- Monitor outbound admin actions with a web application firewall (WAF) rule that flags cross-origin POST requests to wp-admin.
- Alert on modifications to theme files or database options tied to the Bard theme outside scheduled maintenance windows.
How to Mitigate CVE-2025-64368
Immediate Actions Required
- Identify all WordPress installations using the Bard theme at version 1.6 or earlier.
- Restrict administrator browsing habits and enforce separation between admin sessions and general web browsing.
- Deploy a WAF rule to block cross-origin POST requests targeting Bard theme admin endpoints.
Patch Information
No fixed version is listed in the NVD entry at the time of publication. Administrators should monitor the Patchstack advisory and the vendor's channels for an official patched release beyond version 1.6. Until a patched version is confirmed, apply the workarounds below.
Workarounds
- Log out of WordPress administrator sessions when not actively managing the site to reduce the CSRF exposure window.
- Use browser isolation or a dedicated browser profile for WordPress administration to prevent malicious pages from reaching authenticated sessions.
- Consider replacing the Bard theme with an actively maintained alternative if a patch is not released promptly.
- Enforce SameSite=Lax or SameSite=Strict cookie attributes on WordPress authentication cookies where supported.
