CVE-2025-67517: 
WordPress vulnerability analysis and mitigation

CVE-2025-67517 is a Blind SQL Injection vulnerability in the ArtPlacer Widget WordPress plugin (by artplacer) affecting all versions through 2.22.9.2. The vulnerability was reported by researcher Jarno Vos (jrn5151) on October 24, 2025, published by Patchstack on November 23, 2025, and assigned a CVE on December 9, 2025. It carries a CVSS v3.1 base score of 8.5 (High) (Patchstack).

The vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), enabling Blind SQL Injection attacks. A low-privileged authenticated user (Contributor or Developer role) can inject malicious SQL commands through network-accessible plugin functionality without requiring user interaction. Because the injection is "blind," the attacker infers database contents through boolean-based or time-based response differences rather than direct output. No detailed technical write-up or public PoC code has been identified at this time (Patchstack).

Successful exploitation allows a low-privileged attacker to read sensitive data from the WordPress database — including user credentials, personal information, and site configuration — with high confidentiality impact. The vulnerability has a changed scope, meaning the impact can extend beyond the plugin itself to the broader database system. Availability is also marginally affected (low impact), though integrity is not directly impacted by this vulnerability (Patchstack).

No public proof-of-concept exploit code has been identified, and there is no evidence of active in-the-wild exploitation at this time. The EPSS score is approximately 0.021% (0.000210), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires at minimum a Contributor or Developer-level WordPress account, which limits opportunistic mass exploitation (Patchstack).

1. Reconnaissance: Identify WordPress sites running the ArtPlacer Widget plugin version ≤ 2.22.9.2 using tools like WPScan or Shodan with WordPress plugin fingerprinting.
2. Obtain low-privileged access: Acquire or register a Contributor or Developer account on the target WordPress site (e.g., via open registration or credential compromise).
3. Identify injectable parameter: Interact with the ArtPlacer Widget plugin's functionality as an authenticated user and identify the input parameter(s) susceptible to SQL injection.
4. Craft blind SQL injection payload: Construct boolean-based or time-based blind SQL injection payloads (e.g., using AND SLEEP(5) for time-based or conditional AND 1=1/AND 1=2 for boolean-based) to confirm injection.
5. Extract database contents: Use automated tools such as sqlmap with session cookies to enumerate the database schema and extract sensitive data (e.g., WordPress wp_users table containing hashed passwords and email addresses).
6. Leverage extracted data: Use extracted credentials or sensitive information for further account takeover or lateral movement within the WordPress environment (Patchstack).

• Network: Unusual or repeated HTTP requests to ArtPlacer Widget plugin endpoints containing SQL metacharacters (e.g., ', --, SLEEP, UNION, AND 1=), particularly from authenticated low-privileged user sessions.
• Logs: WordPress or web server access logs showing abnormal query patterns or time-delayed responses (indicative of time-based blind SQLi) from Contributor/Developer accounts; database error messages in WordPress debug logs.
• Database: Unexpected or unauthorized database queries logged in MySQL/MariaDB slow query logs, particularly those involving SLEEP(), BENCHMARK(), or conditional logic targeting wp_users or other sensitive tables.
• Process: Unusual database load spikes or slow query alerts correlating with authenticated plugin interactions.

The vulnerability is patched in ArtPlacer Widget version 2.23. Site administrators should update the plugin to version 2.23 or later immediately via the WordPress admin dashboard or by downloading the updated plugin from the WordPress plugin repository. If an immediate update is not possible, consider restricting Contributor/Developer account registration, implementing a Web Application Firewall (WAF) with SQL injection rules, and applying the principle of least privilege to the WordPress database account. Patchstack users can enable auto-update for vulnerable plugins as an additional safeguard (Patchstack).
