CVE-2025-52834 is a critical SQL Injection vulnerability (CWE-89) affecting the favethemes Homey product, specifically versions up to 2.4.5. SQL Injection occurs when an application improperly neutralizes special elements in SQL commands, allowing an attacker to inject malicious SQL code. This vulnerability enables remote attackers to execute arbitrary SQL queries on the backend database without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The vulnerability has a CVSS score of 9.3, reflecting its critical severity. The scope is classified as 'Changed' (S:C), meaning exploitation can affect resources beyond the vulnerable component, potentially impacting the entire database or connected systems. While no known exploits are currently reported in the wild, the ease of exploitation and the critical impact on confidentiality make this a high-risk issue. The vulnerability could allow attackers to extract sensitive data, such as user credentials, personal information, or configuration details, without altering data integrity but with some potential for limited availability impact. The lack of available patches at the time of publication increases the urgency for mitigation.

For European organizations using favethemes Homey, this vulnerability poses a significant risk to data confidentiality, potentially exposing sensitive customer or business data stored in backend databases. Given the critical CVSS score and the lack of required privileges or user interaction, attackers can remotely exploit this flaw to conduct data breaches, leading to regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial penalties. The partial impact on availability could disrupt services, affecting business continuity. Organizations in sectors such as e-commerce, real estate, or any industry relying on Homey for website themes or content management are particularly vulnerable. The exposure of confidential data could also facilitate further attacks, including identity theft or targeted phishing campaigns within European markets.

Immediate mitigation should focus on applying any available patches or updates from favethemes once released. In the absence of patches, organizations should implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting Homey endpoints. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters interacting with SQL queries. Employ the principle of least privilege for database accounts used by Homey, restricting permissions to only necessary operations to limit potential damage. Regularly audit and monitor database logs for suspicious queries indicative of injection attempts. Additionally, consider isolating the Homey application environment to minimize lateral movement in case of compromise. Engage in proactive vulnerability scanning and penetration testing focused on SQL injection vectors to identify and remediate weaknesses promptly.
