CVE-2025-12502: 
WordPress vulnerability analysis and mitigation

CVE-2025-12502 is a SQL injection vulnerability in the attention-bar WordPress plugin affecting all versions through 0.7.2.1. The flaw allows authenticated users with Contributor-level privileges or higher (including administrators) to perform SQL injection attacks via an unsanitized parameter passed directly into a SQL statement. It was publicly disclosed on October 30, 2025, and assigned a CVSS v3.1 base score of 6.8 (Medium) (WPScan, Red Hat CVE). The vulnerability was discovered and reported by researchers Yousof Nahya and Hamza Nour (WPScan).

The root cause is improper neutralization of special elements used in an SQL command (CWE-89), where the plugin fails to sanitize or escape user-supplied input before incorporating it into a database query. The vulnerable endpoint is the admin page wp-admin/admin.php?page=pd_nb_entries with the delete action, where the id parameter is injectable. A time-based blind SQL injection proof-of-concept demonstrates the issue: navigating to https://example.com/wp-admin/admin.php?page=pd_nb_entries&delete&id=14+OR+(SELECT+42+FROM+(SELECT(SLEEP(5)))b) causes a measurable 5-second delay in the server response, confirming blind SQLi (WPScan). The attack vector is network-based with low attack complexity, requiring high privileges (Contributor role or above) and no user interaction (Red Hat CVE).

Successful exploitation allows authenticated attackers to extract sensitive data from the WordPress database, including user credentials, email addresses, private post content, and configuration data. The CVSS scope is marked as Changed, indicating the impact can extend beyond the plugin itself to the broader WordPress database and potentially the underlying server environment. Confidentiality impact is rated High, while integrity and availability are not directly affected by this vulnerability (WPScan, Red Hat CVE).

A verified proof-of-concept demonstrating time-based blind SQL injection is publicly available via WPScan (WPScan). No evidence of active in-the-wild exploitation or threat actor attribution has been reported at this time. The EPSS score is approximately 0.021% (0.000210), indicating a 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-level WordPress account, which limits opportunistic mass exploitation but remains a realistic risk in multi-author WordPress environments.

1. Reconnaissance: Identify WordPress sites running the attention-bar plugin (version ≤ 0.7.2.1) using tools like WPScan (wpscan --url https://target.com --enumerate p) or by checking /wp-content/plugins/attention-bar/ for plugin presence.
2. Obtain credentials: Acquire or already possess a WordPress account with at least Contributor-level privileges (e.g., via registration on open-registration sites, credential stuffing, or phishing).
3. Authenticate: Log in to the WordPress admin panel at https://target.com/wp-login.php using the obtained credentials.
4. Trigger the vulnerable endpoint: Navigate to the vulnerable admin page: https://target.com/wp-admin/admin.php?page=pd_nb_entries&delete&id=14.
5. Inject SQL payload: Append a time-based blind SQL injection payload to the id parameter, e.g., id=14+OR+(SELECT+42+FROM+(SELECT(SLEEP(5)))b). A 5-second response delay confirms the injection point is active (WPScan).
6. Extract data: Use automated tools such as sqlmap with the authenticated session cookie to enumerate and dump database tables, including wp_users (usernames, hashed passwords, emails) and other sensitive data: sqlmap -u 'https://target.com/wp-admin/admin.php?page=pd_nb_entries&delete&id=14' --cookie='wordpress_logged_in=...' --dbs.
7. Post-exploitation: Use extracted password hashes for offline cracking or leverage database access to escalate privileges within the WordPress application.

• Network: Unusual GET requests to /wp-admin/admin.php?page=pd_nb_entries&delete&id= containing SQL keywords (SELECT, SLEEP, UNION, OR, FROM) or URL-encoded equivalents (%28SELECT, %29, %2B) in web server access logs.
• Logs: WordPress or web server access logs showing repeated requests to the pd_nb_entries admin page with anomalous id parameter values, especially with time delays between request and response suggesting SLEEP-based injection; multiple requests from the same authenticated session with varying id payloads.
• Database: Unexpected or high-volume database query activity originating from the WordPress application user, particularly queries involving SLEEP(), BENCHMARK(), or UNION SELECT patterns in MySQL slow query logs or general query logs.
• Process: Unusual database load spikes or query timeouts correlating with web requests to the attention-bar admin endpoint.

As of the time of disclosure, no patched version was listed in the WPScan advisory ("No known fix"), though Feedly intelligence notes a fix is available in version 0.7.3 and later (WPScan). Site administrators should update the attention-bar plugin to version 0.7.3 or later if available, or deactivate and remove the plugin until a verified patch is released. As a workaround, restrict Contributor-level user registration and audit existing Contributor accounts to minimize the attack surface. Implement a Web Application Firewall (WAF) rule to block SQL injection patterns in requests targeting the pd_nb_entries admin page.

The vulnerability was reported by independent researchers Yousof Nahya and Hamza Nour and verified by WPScan (WPScan). No significant vendor statements, notable researcher commentary beyond the original disclosure, or major media coverage have been identified for this vulnerability.
