CVE-2025-54008 Overview
CVE-2025-54008 is a sensitive information disclosure vulnerability in the Crocoblock JetSmartFilters WordPress plugin. The flaw affects all versions of jet-smart-filters up to and including 3.6.7. An authenticated attacker with low-level privileges can retrieve embedded sensitive data that the plugin exposes through server responses. The issue is classified under [CWE-201: Insertion of Sensitive Information Into Sent Data].
Critical Impact
Authenticated users with minimal privileges can extract sensitive information embedded in plugin-generated responses, breaching confidentiality of site data on affected WordPress installations.
Affected Products
- Crocoblock JetSmartFilters WordPress plugin
- All versions from n/a through 3.6.7
- WordPress sites running the vulnerable jet-smart-filters package

Technical Details for CVE-2025-54008
Vulnerability Analysis
The vulnerability stems from the JetSmartFilters plugin including sensitive information in data sent to authenticated users. The plugin fails to properly restrict which fields are serialized into responses that filter requests generate. Because the exposure occurs through legitimate plugin endpoints, attackers do not need to bypass authentication mechanisms beyond obtaining a low-privilege account.
An attacker with a subscriber-level or comparable account can query filter functionality and inspect the returned payloads. The responses contain embedded data that should remain server-side. This creates a confidentiality breach without impacting integrity or availability.
Root Cause
The root cause is improper output filtering within the plugin's response generation logic. Sensitive fields are serialized alongside intended filter data instead of being scrubbed prior to transmission. [CWE-201] specifically describes this pattern where sensitive information is embedded in resources returned to less-privileged actors.
Attack Vector
Exploitation requires network access and authenticated session context with low privileges. No user interaction is required. The attacker interacts with the vulnerable plugin endpoint and parses returned data for sensitive values. Refer to the Patchstack Vulnerability Report for advisory details.
Detection Methods for CVE-2025-54008
Indicators of Compromise
- Unusual volume of authenticated requests to JetSmartFilters AJAX endpoints from a single user account.
- Response payloads from jet-smart-filters endpoints containing fields not typically rendered in the UI.
- Low-privilege accounts issuing repeated filter queries with parameter enumeration patterns.
Detection Strategies
- Review WordPress access logs for repeated authenticated calls to admin-ajax.php referencing jet_smart_filters actions.
- Compare plugin response sizes across sessions to identify anomalies indicating extra embedded data.
- Audit WordPress user roles and correlate low-privilege sessions with high-volume filter API activity.
Monitoring Recommendations
- Enable verbose logging on the web server for plugin-related endpoints and forward events to a centralized SIEM.
- Alert on subscriber-tier accounts issuing more than a defined threshold of filter requests per minute.
- Track outbound response body sizes from jet-smart-filters endpoints to detect data amplification patterns.
How to Mitigate CVE-2025-54008
Immediate Actions Required
- Identify all WordPress installations running jet-smart-filters version 3.6.7 or earlier.
- Restrict registration of new low-privilege accounts until patched.
- Rotate any credentials, API keys, or tokens that the plugin may have exposed through its responses.
Patch Information
At the time of NVD publication, the advisory covers versions up to and including 3.6.7. Administrators should consult the Patchstack Vulnerability Report and upgrade to the latest available version of JetSmartFilters published by Crocoblock.
Workarounds
- Temporarily deactivate the JetSmartFilters plugin until an upgrade is applied.
- Apply web application firewall rules that block or throttle authenticated requests to jet_smart_filters AJAX actions.
- Enforce least-privilege on all WordPress accounts and audit subscriber-tier access.
# Configuration example: disable the plugin via WP-CLI
wp plugin deactivate jet-smart-filters
wp plugin status jet-smart-filters
