CVE-2025-49055: 
WordPress vulnerability analysis and mitigation

CVE-2025-49055 is a Blind SQL Injection vulnerability in the WP Lead Capturing Pages WordPress plugin (wp-lead-capture) developed by kamleshyadav. It affects all versions of the plugin through version 2.5, with no official patch currently available. The vulnerability was reported by researcher João Pedro S Alcântara (Kinorth) on August 31, 2025, and published by Patchstack on January 8, 2026. It carries a CVSS v3.1 base score of 9.3 (Critical), assigned by Patchstack (Patchstack).

The vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), enabling Blind SQL Injection attacks. Because the plugin fails to properly sanitize or parameterize user-supplied input before incorporating it into database queries, an unauthenticated remote attacker can craft malicious HTTP requests to infer database contents through boolean- or time-based blind techniques. No authentication or user interaction is required, and the attack vector is fully network-accessible, making it trivially exploitable against any exposed WordPress installation running the affected plugin (Patchstack).

Successful exploitation allows unauthenticated attackers to extract sensitive data from the WordPress database, including user credentials, personal information, and any data stored by the plugin or other WordPress components. The CVSS scope is rated as Changed, meaning the impact extends beyond the plugin itself to the underlying database and potentially other hosted applications sharing the same database instance. Confidentiality impact is rated High, with a Low availability impact due to potential database performance degradation from repeated injection queries; integrity is not directly affected by this specific attack vector (Patchstack).

As of the latest available intelligence, there is no public proof-of-concept exploit code and no confirmed in-the-wild exploitation of CVE-2025-49055. The EPSS score is approximately 0.021%, indicating a currently low probability of near-term exploitation. However, Patchstack classifies this as high priority and notes that vulnerabilities of this type are frequently used in mass-exploit campaigns targeting WordPress sites at scale. No threat actor attribution has been reported, and the vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) catalog (Patchstack).

1. Reconnaissance: Identify WordPress sites running the WP Lead Capturing Pages plugin (wp-lead-capture) version 2.5 or earlier using tools like WPScan, Shodan, or by checking publicly accessible plugin metadata at /wp-content/plugins/wp-lead-capture/readme.txt.
2. Identify injectable endpoint: Probe the plugin's front-end or AJAX-facing endpoints for parameters that interact with the database (e.g., form submission or lead capture endpoints exposed by the plugin).
3. Craft blind SQL injection payload: Construct boolean-based or time-based blind SQL injection payloads (e.g., using AND SLEEP(5)-- or conditional expressions) to confirm the injection point without receiving direct query output.
4. Extract database contents: Use automated tools such as sqlmap with the identified endpoint and parameter to enumerate databases, tables, and columns, then dump sensitive data such as WordPress user credentials (wp_users table).
5. Leverage extracted credentials: Use extracted password hashes for offline cracking or attempt credential reuse against the WordPress admin panel or other services (Patchstack).

• Network: Unusual or repeated HTTP requests to WP Lead Capturing Pages plugin endpoints containing SQL metacharacters (e.g., single quotes, AND, OR, SLEEP, BENCHMARK, UNION) in query parameters or POST body fields.
• Logs: WordPress or web server access logs showing high volumes of requests to plugin-specific URLs with anomalous parameter values; time-delayed responses (indicative of SLEEP()-based blind injection) from the web server.
• Database: Unexpected spikes in database query execution time; database error logs showing malformed SQL queries originating from WordPress plugin queries.
• File System: Presence of the plugin directory /wp-content/plugins/wp-lead-capture/ on installations where the plugin should not be present or is outdated.

No official patch is currently available for the WP Lead Capturing Pages plugin. Organizations should immediately disable or remove the plugin from all WordPress installations until a patched version is released. Patchstack has issued a virtual patching/mitigation rule for subscribers to block exploitation attempts in the interim. Additional mitigations include deploying a Web Application Firewall (WAF) with SQL injection detection rules, applying the principle of least privilege to the WordPress database account, and monitoring database query logs for anomalous activity (Patchstack).

Wordfence included CVE-2025-49055 in its weekly WordPress vulnerability intelligence report covering January 5–11, 2026, highlighting it as part of broader WordPress plugin security concerns. Patchstack, the discovering and reporting organization, classified the vulnerability as high priority and noted its potential for use in mass-exploit campaigns. No significant independent researcher commentary or broader media coverage has been identified beyond these security vendor reports.
