CVE-2025-5019: Hive Support Plugin CSRF Vulnerability

CVE-2025-5019 Overview

CVE-2025-5019 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the Hive Support | AI-Powered Help Desk, Live Chat & AI Chat Bot Plugin for WordPress. All versions up to and including 1.2.5 are vulnerable. The flaw exists in the hs_update_ai_chat_settings() function, which lacks proper nonce validation. Unauthenticated attackers can reconfigure the plugin's AI and chat settings, including API keys, by tricking a site administrator into clicking a crafted link. Successful exploitation can redirect notifications or leak data to attacker-controlled endpoints.

Critical Impact
Attackers who successfully forge an authenticated administrator request can overwrite AI/chat configuration, exfiltrate API keys, and redirect help-desk data to endpoints under their control.

Affected Products

Hive Support | AI-Powered Help Desk, Live Chat & AI Chat Bot Plugin for WordPress
All plugin versions through 1.2.5
WordPress sites with the plugin active and an authenticated administrator session

Technical Details for CVE-2025-5019

Vulnerability Analysis

The vulnerability is a Cross-Site Request Forgery flaw in the plugin's AJAX handler responsible for updating AI chat settings. The hs_update_ai_chat_settings() function processes administrator configuration changes without verifying a WordPress nonce. Without nonce validation, the server cannot confirm the request originated from an authorized administrative UI action. An attacker who hosts or injects a malicious page can cause an authenticated administrator's browser to submit a state-changing request to the target site.

The impact extends beyond configuration tampering. Because the affected settings include API keys and notification endpoints, forged requests can be used to swap legitimate integrations for attacker-controlled ones. This routes future support tickets, chat transcripts, and AI processing through an adversary-owned infrastructure.

Root Cause

The root cause is missing or incorrect nonce validation on the hs_update_ai_chat_settings() AJAX action. WordPress plugins are expected to call check_ajax_referer() or wp_verify_nonce() on state-changing endpoints. The vulnerable handler processes POST parameters and persists them to plugin options without confirming request authenticity. Reference the vulnerable code path in the WordPress Plugin Code Review.

Attack Vector

Exploitation requires user interaction. The attacker crafts a page containing a hidden form or JavaScript that issues a POST request to the target WordPress site's admin-ajax.php endpoint with the vulnerable action. When an authenticated administrator visits the attacker's page or clicks a malicious link, the browser attaches session cookies and submits the request. The plugin accepts and applies the changes because no nonce check gates the handler. No credentials or prior authentication are required from the attacker.

See the vulnerability description in prose above. No verified public exploit code is available.

Detection Methods for CVE-2025-5019

Indicators of Compromise

Unexpected modifications to Hive Support plugin options, particularly api_key, webhook URLs, or notification endpoints in the WordPress wp_options table
Outbound HTTP requests from the WordPress host to unfamiliar domains referenced in the chat plugin configuration
Administrator sessions loading external pages shortly before configuration changes appear in audit logs

Detection Strategies

Review web server access logs for POST requests to admin-ajax.php with the hs_update_ai_chat_settings action and a Referer header from an external domain
Compare current plugin settings against a known-good baseline to identify unauthorized changes to AI keys or endpoints
Alert on WordPress option changes to Hive Support keys using a file integrity or database monitoring tool

Monitoring Recommendations

Enable WordPress audit logging (via a security plugin) to capture option changes and administrator actions with timestamps and originating IPs
Monitor outbound network traffic from the WordPress server for connections to newly seen third-party AI or webhook endpoints
Track administrator browser activity for cross-origin POST requests targeting admin-ajax.php

How to Mitigate CVE-2025-5019

Immediate Actions Required

Update the Hive Support plugin to a version later than 1.2.5 once the vendor releases a patched build referenced in the WordPress Changeset Update
Rotate any API keys previously stored in the plugin configuration, as they may have been exposed through a forged request
Audit the plugin's current settings and restore legitimate notification endpoints and integrations

Patch Information

Review vendor guidance and update notes on the WordPress Plugin Developer Info page. Confirm the installed version has nonce validation applied to hs_update_ai_chat_settings() before returning the plugin to production use. Additional analysis is available in the Wordfence Vulnerability Report.

Workarounds

Deactivate the Hive Support plugin until an updated version with proper nonce validation is installed
Restrict WordPress administrator accounts to dedicated browsers or sessions that do not browse untrusted content
Deploy a web application firewall rule that blocks POST requests to admin-ajax.php with the hs_update_ai_chat_settings action when no valid nonce parameter is present

bash

# Example WAF rule (ModSecurity) to block requests missing a nonce
SecRule REQUEST_URI "@contains /wp-admin/admin-ajax.php" \
  "chain,deny,status:403,id:1005019,msg:'Block Hive Support CSRF CVE-2025-5019'"
  SecRule ARGS:action "@streq hs_update_ai_chat_settings" \
    "chain"
    SecRule &ARGS:_wpnonce "@eq 0"
