CVE-2025-9587 is a medium severity SQL Injection vulnerability identified in the CTL Behance Importer Lite WordPress plugin, specifically affecting versions up to 1.0. The vulnerability arises because the plugin fails to properly sanitize and escape user-supplied input before incorporating it into SQL queries executed via an AJAX action. Notably, this AJAX endpoint is accessible to unauthenticated users, meaning that an attacker does not require any credentials or prior access to exploit this flaw. The vulnerability is classified under CWE-89, which corresponds to SQL Injection, a critical class of injection flaws that allow attackers to manipulate backend SQL queries. The CVSS v3.1 base score is 6.5, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). Exploiting this vulnerability could allow an attacker to execute arbitrary SQL commands, potentially leading to unauthorized data disclosure or modification within the WordPress database. However, no known exploits are currently reported in the wild, and no official patches or updates have been published as of the vulnerability disclosure date (October 2, 2025).

For European organizations using WordPress websites with the CTL Behance Importer Lite plugin installed, this vulnerability poses a tangible risk of data compromise. The SQL Injection flaw could enable attackers to extract sensitive information such as user credentials, personal data, or proprietary content stored in the WordPress database, violating GDPR and other data protection regulations prevalent in Europe. Additionally, attackers might alter or corrupt data, undermining data integrity and potentially damaging organizational reputation. Since the vulnerability is exploitable without authentication and requires no user interaction, automated attacks or mass scanning campaigns could target vulnerable sites, increasing the risk of widespread exploitation. The impact is particularly significant for organizations relying on WordPress for public-facing websites or client portals, where data confidentiality and integrity are paramount. Although availability is not directly affected, the indirect consequences of data breaches and regulatory non-compliance could lead to financial penalties and loss of customer trust.

European organizations should immediately audit their WordPress installations to identify the presence of the CTL Behance Importer Lite plugin, especially versions up to 1.0. Since no official patches are currently available, organizations should consider the following specific mitigations: 1) Disable or remove the CTL Behance Importer Lite plugin until a secure update is released. 2) Implement Web Application Firewall (WAF) rules tailored to detect and block suspicious SQL injection patterns targeting AJAX endpoints, particularly those related to this plugin. 3) Employ input validation and sanitization at the web server or reverse proxy level as a temporary safeguard. 4) Monitor web server logs and intrusion detection systems for anomalous requests targeting the AJAX action of the plugin. 5) Engage with the plugin vendor or WordPress security community to track patch releases and apply updates promptly once available. 6) Conduct regular security assessments and penetration testing focusing on WordPress plugins to proactively identify similar vulnerabilities. These measures go beyond generic advice by focusing on immediate containment, detection, and proactive monitoring specific to this plugin and vulnerability.
