CVE-2025-26755 identifies a Blind SQL Injection vulnerability in the WP Airbnb Review Slider plugin for WordPress, developed by jgwhite33, affecting versions up to and including 3.9. The vulnerability arises from improper neutralization of special characters in SQL commands, allowing attackers to craft malicious input that alters the intended SQL query logic executed by the plugin. Blind SQL Injection means attackers cannot directly see query results but can infer data through time delays or boolean responses, enabling extraction of sensitive database information over time. The plugin is used to display Airbnb reviews on WordPress websites, and the injection point likely exists in parameters processed by the plugin’s backend code. No CVSS score has been assigned yet, and no public exploits are known, but the vulnerability is publicly disclosed and considered exploitable. The flaw compromises the confidentiality and integrity of the database, potentially exposing user data, review content, or administrative credentials stored within the WordPress database. Exploitation does not require user interaction but may depend on the attacker’s ability to send crafted requests to the vulnerable plugin endpoints. The lack of a patch link indicates that a fix is pending or not yet publicly available. Organizations using this plugin should consider the risk of data leakage and unauthorized database manipulation until remediation is applied.

The impact of this Blind SQL Injection vulnerability is significant for organizations running WordPress sites with the WP Airbnb Review Slider plugin. Attackers could exploit this flaw to extract sensitive information such as user credentials, personal data, or business-critical content stored in the WordPress database. They could also potentially modify or delete data, leading to integrity loss and disruption of website functionality. For businesses relying on Airbnb reviews to build customer trust, data manipulation could damage reputation and customer confidence. Additionally, attackers might leverage this vulnerability as a pivot point for further compromise of the hosting environment or network. The absence of authentication requirements or user interaction lowers the barrier to exploitation, increasing risk. While no active exploits are reported, the public disclosure raises the likelihood of future attacks. Organizations worldwide using this plugin are at risk, especially those in the hospitality, travel, and tourism sectors where Airbnb integrations are common.

To mitigate this vulnerability, organizations should immediately audit their WordPress installations for the presence of the WP Airbnb Review Slider plugin and identify the version in use. If a patched version is released, promptly update to the latest version. In the absence of an official patch, manual code review and sanitization of all inputs processed by the plugin should be performed, employing parameterized queries or prepared statements to prevent SQL injection. Web application firewalls (WAFs) can be configured to detect and block suspicious SQL injection patterns targeting the plugin’s endpoints. Additionally, restrict access to the plugin’s administrative and input interfaces to trusted users only. Regularly monitor logs for anomalous database query patterns or repeated failed attempts that may indicate exploitation attempts. Backup WordPress databases frequently to enable recovery in case of data tampering. Finally, consider disabling or removing the plugin if it is not essential to reduce attack surface.
