CVE-2025-67931 Overview
CVE-2025-67931 is a sensitive data exposure vulnerability in the AITpro BulletProof Security plugin for WordPress. The flaw allows unauthenticated attackers to retrieve embedded sensitive information from data sent by the plugin. The vulnerability is classified under [CWE-201]: Insertion of Sensitive Information Into Sent Data. All versions of bulletproof-security up to and including 6.9 are affected. The issue is exploitable over the network without authentication or user interaction, exposing site secrets that can support follow-on attacks against the WordPress installation.
Critical Impact
Unauthenticated network-based retrieval of sensitive data from WordPress sites running BulletProof Security 6.9 or earlier, with no user interaction required.
Affected Products
- AITpro BulletProof Security plugin for WordPress, versions up to and including 6.9
- WordPress sites with bulletproof-security installed and active
- All deployments where the plugin is reachable over the network

Technical Details for CVE-2025-67931
Vulnerability Analysis
The vulnerability stems from the BulletProof Security plugin including sensitive information in data it transmits to clients or external endpoints. An unauthenticated attacker can issue network requests to the plugin and observe embedded secrets in the responses. The flaw maps to [CWE-201], where confidential data is unintentionally included in messages, logs, or HTTP responses produced by the application. According to EPSS data dated 2026-05-14, exploitation likelihood is low, and no public exploit or CISA KEV listing exists at this time. The exposure undermines confidentiality protections of the WordPress site and may reveal information used to harden subsequent attack stages.
Root Cause
The root cause is improper handling of sensitive values inside data the plugin emits. The plugin embeds information that should remain server-side into responses or other outbound channels accessible to unauthenticated requesters. No access control or filtering removes the sensitive content before transmission.
Attack Vector
An attacker sends crafted HTTP requests over the network to a WordPress site running bulletproof-security 6.9 or earlier. The plugin returns responses that contain embedded sensitive data. The attacker parses the responses to extract the exposed information. No credentials, privileges, or victim interaction are required.
No verified proof-of-concept code is published. Refer to the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-67931
Indicators of Compromise
- Unauthenticated HTTP GET or POST requests to bulletproof-security plugin endpoints under /wp-content/plugins/bulletproof-security/
- Outbound responses from the WordPress site containing configuration values, internal paths, or other secrets
- Repeated requests from a single source enumerating plugin URLs or admin-ajax actions tied to BulletProof Security
Detection Strategies
- Inventory WordPress installations and identify any running bulletproof-security version <= 6.9
- Inspect web server access logs for unauthenticated requests to plugin paths returning unusually large or sensitive payloads
- Deploy web application firewall rules that flag responses containing keys, tokens, or filesystem paths originating from plugin endpoints
Monitoring Recommendations
- Forward WordPress and reverse proxy logs to a centralized analytics platform and alert on plugin path access patterns
- Monitor for scanning behavior targeting /wp-content/plugins/bulletproof-security/ across multiple sites
- Track plugin version metadata across WordPress fleets to surface hosts still on vulnerable releases
How to Mitigate CVE-2025-67931
Immediate Actions Required
- Identify all WordPress sites running bulletproof-security and confirm the installed version
- Update BulletProof Security to a fixed release once published by AITpro, or temporarily deactivate the plugin if no patched version is available
- Rotate any credentials, API keys, or secrets that may have been exposed through the plugin
Patch Information
The vulnerability affects BulletProof Security versions up to and including 6.9. Monitor the Patchstack Vulnerability Report and the AITpro plugin page on WordPress.org for an official fixed version, and apply the update across all affected sites.
Workarounds
- Deactivate and remove the bulletproof-security plugin until a patched release is installed
- Restrict access to plugin endpoints at the web server or WAF layer to authenticated administrators only
- Audit and rotate any secrets, tokens, or configuration values that the plugin may have exposed
