CVE-2025-32148 Overview
CVE-2025-32148 is an SQL injection vulnerability in the Daisycon prijsvergelijkers WordPress plugin. The flaw affects all plugin versions up to and including 4.8.4. Authenticated attackers with low privileges can inject arbitrary SQL commands into backend database queries. The vulnerability is classified under [CWE-89], Improper Neutralization of Special Elements used in an SQL Command.
Critical Impact
Authenticated attackers can extract sensitive data from the WordPress database and disrupt application availability through crafted SQL queries sent over the network.
Affected Products
- Daisycon prijsvergelijkers WordPress plugin versions up to and including 4.8.4
- WordPress installations running the vulnerable Daisycon price comparison plugin
- Sites exposing plugin endpoints to authenticated users

Technical Details for CVE-2025-32148
Vulnerability Analysis
The Daisycon prijsvergelijkers plugin fails to properly neutralize special characters in user-supplied input before incorporating it into SQL queries. An attacker authenticated to the WordPress instance can submit crafted parameters that alter the structure of backend SQL statements. The scope is marked as changed, meaning a successful exploit can impact resources beyond the vulnerable component itself.
The confidentiality impact is high because attackers can read arbitrary database contents, including WordPress user records, session tokens, and plugin configuration data. Availability is also affected at a limited level through resource-intensive injected queries. The EPSS probability is 0.188% at the 40.4 percentile, indicating limited observed exploitation activity to date.
Root Cause
The root cause is missing parameterization or escaping in SQL query construction within the plugin code. User-controlled input is concatenated directly into SQL statements rather than passed through prepared statements or the WordPress $wpdb->prepare() API. This allows query logic to be modified by attacker-controlled characters such as single quotes, comments, and UNION operators.
Attack Vector
The attack vector is network-based and requires low-privilege authentication on the target WordPress site. No user interaction is required. An attacker submits a malicious request containing SQL metacharacters to a vulnerable plugin endpoint. The injected payload executes within the database context of the WordPress installation, granting access to data stored across the WordPress schema.
No verified public exploit code is available. Technical details are documented in the Patchstack Vulnerability Report.
Detection Methods for CVE-2025-32148
Indicators of Compromise
- Web server access logs containing SQL metacharacters such as ', --, UNION SELECT, or SLEEP( in query parameters targeting Daisycon plugin endpoints
- Unexpected outbound database queries originating from the WordPress PHP process
- Anomalous read volume against the wp_users, wp_usermeta, or wp_options tables
- Authenticated low-privilege accounts generating requests to administrative plugin paths
Detection Strategies
- Deploy a web application firewall rule set tuned to detect SQL injection patterns in requests to /wp-content/plugins/daisycon/ paths
- Enable WordPress and PHP error logging to capture syntax exceptions raised by malformed injected queries
- Inspect database query logs for statements containing concatenated user input or tautologies such as OR 1=1
Monitoring Recommendations
- Forward WordPress, web server, and database logs to a centralized analytics platform for correlation across request, query, and authentication events
- Alert on spikes in 500-series HTTP responses from plugin URLs, which often accompany blind SQL injection probing
- Track plugin version inventory across all WordPress sites to identify hosts still running Daisycon prijsvergelijkers <= 4.8.4
How to Mitigate CVE-2025-32148
Immediate Actions Required
- Identify all WordPress sites running the Daisycon prijsvergelijkers plugin and inventory installed versions
- Update the plugin to a version newer than 4.8.4 once the vendor releases a fixed release
- Restrict access to authenticated plugin endpoints using role-based access controls and IP allow-listing where feasible
- Rotate WordPress administrator credentials and database passwords if compromise is suspected
Patch Information
Refer to the Patchstack Vulnerability Report for current patch status and remediation guidance from the vendor. Apply the fixed version as soon as it becomes available through the WordPress plugin repository.
Workarounds
- Deactivate the Daisycon prijsvergelijkers plugin until a patched version is installed
- Deploy a WAF signature blocking SQL injection patterns directed at plugin URLs
- Reduce the number of authenticated accounts on the WordPress site and audit subscriber-level access
- Apply database-level least privilege so the WordPress database user cannot read tables outside its required scope
# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate daisycon --all
wp plugin status daisycon
