CVE-2025-5590 identifies a critical SQL Injection vulnerability in the Owl carousel responsive plugin for WordPress, developed by gopiplus. The flaw exists in all versions up to and including 1.9 due to improper neutralization of special elements in the 'id' parameter used within SQL commands. Specifically, the plugin fails to adequately escape or prepare SQL queries involving this parameter, allowing authenticated users with Contributor-level access or higher to inject additional SQL commands. This vulnerability is time-based, meaning attackers can infer data by measuring response delays caused by crafted SQL payloads. Exploitation does not require user interaction beyond authentication and can be performed remotely, increasing the attack surface. The vulnerability impacts confidentiality by enabling unauthorized data extraction, integrity by allowing unauthorized query manipulation, and availability by potentially causing database disruptions. The CVSS v3.1 score of 8.8 reflects its high severity, with attack vector as network, low attack complexity, and privileges required at the Contributor level. No patches are currently linked, and no known exploits have been reported in the wild, but the risk remains significant given the plugin's popularity in WordPress sites. The vulnerability is classified under CWE-89, which covers improper neutralization of special elements in SQL commands, a common and dangerous injection flaw.

The impact of CVE-2025-5590 is substantial for organizations using the Owl carousel responsive plugin on WordPress sites. Successful exploitation can lead to unauthorized disclosure of sensitive information stored in the backend database, including user credentials, personal data, or business-critical information. Attackers can also manipulate database queries, potentially altering or deleting data, which compromises data integrity. Additionally, crafted queries could degrade database performance or cause denial of service, impacting availability. Since the vulnerability requires only Contributor-level access, attackers can leverage compromised or weak user accounts to escalate their impact. This threat is particularly critical for websites handling sensitive customer data, e-commerce platforms, and content management systems that rely on this plugin. The widespread use of WordPress globally means that many organizations could be exposed, increasing the risk of large-scale data breaches and reputational damage. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the ease of exploitation and high severity score suggest attackers may develop exploits soon.

To mitigate CVE-2025-5590, organizations should immediately assess their WordPress installations for the presence of the Owl carousel responsive plugin and verify the version in use. Since no official patch is currently available, temporary mitigations include restricting Contributor-level and higher privileges to trusted users only, minimizing the risk of exploitation. Implementing a Web Application Firewall (WAF) with robust SQL Injection detection and prevention rules can help block malicious payloads targeting the 'id' parameter. Additionally, applying strict input validation and sanitization at the application level, if possible, can reduce exposure. Monitoring database logs and query patterns for unusual or time-delayed queries can aid in early detection of exploitation attempts. Organizations should also prepare to update or replace the plugin once a vendor patch is released. Regular backups and incident response plans should be reviewed and tested to ensure rapid recovery in case of compromise. Finally, educating site administrators about the risks of privilege escalation and enforcing strong authentication policies will further reduce attack vectors.
