CVE-2025-30546 Overview
CVE-2025-30546 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the boroV Cackle plugin for WordPress. The issue affects Cackle versions from an unspecified initial release through version 4.33. The vulnerability is classified under CWE-352, which covers missing or improper CSRF protections.
An attacker can craft a malicious web page that, when visited by an authenticated user, submits state-changing requests to a vulnerable Cackle installation. Successful exploitation requires user interaction and results in a limited integrity impact with no confidentiality or availability impact.
Critical Impact
Attackers can trigger unauthorized state-changing actions in the Cackle plugin by luring an authenticated WordPress user to a malicious page.
Affected Products
- boroV Cackle WordPress plugin, versions up to and including 4.33
- WordPress sites with the Cackle comments plugin installed and activated
- Any Cackle deployment that has not been updated beyond version 4.33
Discovery Timeline
- 2025-03-24 - CVE-2025-30546 published to the National Vulnerability Database

Technical Details for CVE-2025-30546
Vulnerability Analysis
CVE-2025-30546 is a Cross-Site Request Forgery flaw ([CWE-352]) in the boroV Cackle WordPress plugin. The plugin fails to validate the origin of state-changing HTTP requests, allowing an attacker to forge requests that appear to come from an authenticated user. Exploitation is performed remotely over the network and requires the target to interact with attacker-controlled content, such as clicking a link or loading a crafted page.
The practical impact is limited to unauthorized modifications available to the victim's account context within the Cackle plugin. No sensitive data disclosure or service disruption is expected from a direct CSRF trigger. The EPSS probability score sits at 0.197%, indicating a low predicted likelihood of active exploitation.
Root Cause
The root cause is the absence of adequate anti-CSRF controls on privileged plugin endpoints. WordPress plugins typically enforce request authenticity using wp_nonce_field() and check_admin_referer() or wp_verify_nonce(). When these checks are missing or improperly validated, the plugin accepts cross-origin requests carrying the victim's session cookies. Cackle versions up to 4.33 do not sufficiently enforce these nonce or referer checks for the affected actions.
Attack Vector
The attack is delivered over the network and requires user interaction. An attacker hosts a malicious page containing hidden HTML forms or JavaScript that auto-submits requests to the vulnerable Cackle endpoint. When an authenticated WordPress administrator or privileged user visits the page, the browser automatically attaches their session cookies. The Cackle plugin then processes the forged request as legitimate. Refer to the Patchstack advisory for full technical context.
Detection Methods for CVE-2025-30546
Indicators of Compromise
- Unexpected configuration changes in the Cackle plugin settings without corresponding administrator activity in access logs
- HTTP POST requests to Cackle plugin endpoints with Referer headers pointing to external, untrusted domains
- Web server logs showing authenticated requests to /wp-admin/admin.php?page=cackle* originating from cross-origin contexts
Detection Strategies
- Inspect WordPress access logs for requests to Cackle admin endpoints missing valid _wpnonce parameters
- Correlate administrator browsing history with plugin configuration changes to identify forged requests
- Deploy web application firewall rules that flag cross-origin POST requests targeting /wp-admin/ endpoints without matching referer values
Monitoring Recommendations
- Enable WordPress audit logging to track plugin configuration changes and administrator actions
- Monitor outbound links in comments and email notifications that could be used to lure administrators to attacker-controlled pages
- Alert on plugin setting modifications performed outside expected maintenance windows
How to Mitigate CVE-2025-30546
Immediate Actions Required
- Update the Cackle plugin to a version newer than 4.33 as soon as a fixed release is available from the vendor
- Restrict WordPress administrator access to trusted networks and require multi-factor authentication for privileged accounts
- Instruct administrators to log out of WordPress sessions before browsing untrusted sites
Patch Information
Review the Patchstack advisory for CVE-2025-30546 for the latest fixed version and remediation guidance. Apply the patched release across all WordPress sites running Cackle. Verify the plugin version after upgrade to confirm remediation.
Workarounds
- Deactivate and remove the Cackle plugin until a patched version can be installed
- Deploy a web application firewall rule requiring a same-origin Referer or Origin header on all /wp-admin/POST requests
- Use browser session isolation or dedicated administrative browsers to reduce the chance of an authenticated session being available to malicious pages
