CVE-2025-59554: Advanced Ads Tracking SQLi Vulnerability

CVE-2025-59554 Overview

CVE-2025-59554 is an unauthenticated SQL injection vulnerability affecting the Advanced Ads – Tracking WordPress plugin in versions prior to 3.0.7. The flaw is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). An unauthenticated remote attacker can inject arbitrary SQL into backend database queries over the network without user interaction. The vulnerability carries a CVSS 3.1 base score of 9.3 and a scope change indicator, meaning impact extends beyond the vulnerable component. Patchstack published the advisory tracking this issue.

Critical Impact
Unauthenticated attackers can execute arbitrary SQL queries against the WordPress database, enabling data exfiltration and potential site compromise across affected installations.

Affected Products

Advanced Ads – Tracking plugin for WordPress, versions prior to 3.0.7
WordPress installations with the vulnerable plugin enabled
Any site exposing the plugin's tracking endpoints to the public internet

Technical Details for CVE-2025-59554

Vulnerability Analysis

The vulnerability is an unauthenticated SQL injection in the Advanced Ads – Tracking plugin. The plugin handles ad click and impression tracking events, which require database writes for analytics aggregation. User-supplied input reaches an SQL query without proper parameterization or sanitization. Because the affected endpoint does not require authentication, any remote actor can deliver a crafted payload directly to the vulnerable handler.

The CVSS vector indicates network reachability, low attack complexity, no privileges, and no user interaction. The scope is changed, reflecting impact across trust boundaries within the WordPress stack. Confidentiality impact is high while integrity is rated none and availability low, indicating the primary risk is data exposure rather than direct content tampering. The EPSS score sits at 0.383% with a percentile near 30, signaling moderate near-term exploitation likelihood for a public WordPress plugin flaw.

Root Cause

The root cause is improper neutralization of attacker-controlled input passed into a database query. The plugin concatenates request parameters into SQL statements rather than using prepared statements through $wpdb->prepare(). Tracking parameters such as ad identifiers, referrer values, or campaign identifiers are accepted from public requests and inserted directly into query strings.

Attack Vector

An attacker sends a crafted HTTP request to a tracking endpoint exposed by the plugin. The request carries SQL syntax embedded in a parameter the plugin trusts as a typed value. The database executes the injected clause, allowing UNION-based extraction, time-based blind retrieval, or stacked subqueries against tables such as wp_users and wp_options. Exploitation requires only network access to the WordPress site.

No verified public proof-of-concept code is available. Refer to the Patchstack SQL Injection Advisory for technical details.

Detection Methods for CVE-2025-59554

Indicators of Compromise

HTTP requests to Advanced Ads – Tracking endpoints containing SQL metacharacters such as ', UNION SELECT, SLEEP(, or -- in query or POST parameters
Unexpected reads against wp_users, wp_usermeta, or wp_options tables originating from the plugin's database user
Web server access logs showing repeated parameter-fuzzing patterns against tracking URLs from a single source
New or modified administrator accounts in WordPress shortly after suspicious tracking requests

Detection Strategies

Deploy WAF signatures for SQL injection patterns targeting WordPress plugin endpoints, with specific rules for Advanced Ads – Tracking request paths
Enable MySQL or MariaDB general query logging temporarily to identify malformed queries originating from the plugin
Hunt for outbound database connections returning anomalously large result sets correlated with tracking endpoint hits
Inspect WordPress audit logs for privilege changes or option modifications without corresponding admin sessions

Monitoring Recommendations

Forward web server, WordPress, and database logs to a centralized analytics platform for correlation
Alert on HTTP 500 responses from tracking endpoints, which often indicate SQL syntax errors during injection probing
Baseline normal parameter values for the plugin and flag deviations in length, character classes, or encoding
Review file integrity for wp-content/plugins/advanced-ads-tracking/ to detect tampering after suspected exploitation

How to Mitigate CVE-2025-59554

Immediate Actions Required

Update the Advanced Ads – Tracking plugin to version 3.0.7 or later on every WordPress instance where it is installed
Audit the WordPress database for unauthorized administrator accounts, modified wp_options entries, and suspicious user metadata
Rotate WordPress administrator passwords, API keys, and any secrets stored in the database after patching
Review access logs for the past 90 days for indicators of exploitation attempts against tracking endpoints

Patch Information

The vendor has released version 3.0.7 of the Advanced Ads – Tracking plugin, which remediates the SQL injection. Apply the update through the WordPress plugin manager or by replacing the plugin files directly. Confirm the installed version in the WordPress admin Plugins page after the upgrade. See the Patchstack SQL Injection Advisory for fix details.

Workarounds

Deactivate and remove the Advanced Ads – Tracking plugin until the patched version can be deployed
Restrict access to the plugin's tracking endpoints at the web server or WAF layer to known referrers
Apply a virtual patch through a WAF rule blocking SQL metacharacters in parameters sent to the plugin's URLs
Limit the database privileges of the WordPress MySQL user to the minimum required, denying access to unrelated schemas

bash

# Example WAF rule snippet (ModSecurity) for blocking SQLi against the plugin path
SecRule REQUEST_URI "@contains /advanced-ads-tracking/" \
  "id:1005954,phase:2,deny,status:403,\
  chain,msg:'Possible SQLi against Advanced Ads Tracking (CVE-2025-59554)'"
  SecRule ARGS "@rx (?i)(union\s+select|sleep\(|--\s|';)" "t:none,t:urlDecode"
