CVE-2025-59557 is a critical SQL Injection vulnerability identified in the ThemeMove Learts Addons WordPress plugin, affecting all versions prior to 1.7.5. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing attackers to inject malicious SQL code. This flaw enables unauthenticated remote attackers to execute arbitrary SQL queries on the backend database, potentially leading to unauthorized data disclosure (high confidentiality impact) and limited data integrity compromise. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N) indicates that the attack can be performed over the network without any authentication or user interaction, with a low attack complexity. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. Although no availability impact is noted, the ability to read sensitive data or modify some data poses significant risks. The plugin is commonly used to extend WordPress functionality, often in themes related to e-commerce, portfolios, or media sites. The vulnerability was reserved on 2025-09-17 and published on 2025-10-22, with no known exploits reported yet. Due to the criticality and ease of exploitation, this vulnerability represents a severe threat to websites using the affected plugin versions.

For European organizations, this vulnerability poses a significant risk of data breaches, exposing sensitive customer, employee, or business data stored in backend databases. The high confidentiality impact could lead to exposure of personal data protected under GDPR, resulting in regulatory fines and reputational damage. Partial integrity impact means attackers could alter some data, potentially disrupting business operations or corrupting records. Since the vulnerability requires no authentication or user interaction, any publicly accessible WordPress site using the affected plugin is at risk. This is especially critical for sectors with high online presence such as e-commerce, media, education, and government services. The lack of availability impact reduces risk of denial-of-service, but the potential for data exfiltration and manipulation remains severe. European organizations may also face increased targeted attacks if threat actors weaponize this vulnerability, given the widespread use of WordPress and the plugin in the region.

1. Immediately update the ThemeMove Learts Addons plugin to version 1.7.5 or later once the patch is released by the vendor. 2. If an update is not yet available, temporarily disable the plugin or restrict access to affected endpoints via web application firewalls (WAFs) or IP whitelisting. 3. Implement input validation and sanitization at the application level to prevent malicious SQL inputs. 4. Monitor database logs and web server logs for unusual or suspicious SQL queries indicative of injection attempts. 5. Employ runtime application self-protection (RASP) tools to detect and block injection attacks in real time. 6. Conduct regular security audits and vulnerability scans focusing on WordPress plugins and themes. 7. Educate site administrators on the risks of outdated plugins and enforce strict patch management policies. 8. Consider deploying database activity monitoring solutions to alert on anomalous queries. 9. Backup databases frequently and verify backups to enable recovery in case of data manipulation. 10. Review and harden database user privileges to limit the impact of potential SQL injection exploitation.
