CVE-2025-58686 is a high-severity SQL Injection vulnerability (CWE-89) found in the Perfect Brands for WooCommerce plugin developed by quadlayers. This vulnerability affects all versions up to and including 3.6.0. The flaw arises from improper neutralization of special elements in SQL commands, allowing an attacker with at least low privileges (PR:L) and no user interaction (UI:N) to inject malicious SQL code remotely over the network (AV:N). The vulnerability has a CVSS 3.1 base score of 8.5, indicating a significant security risk. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact is primarily on confidentiality (C:H), with limited impact on availability (A:L) and no impact on integrity (I:N). Exploiting this flaw could allow an attacker to extract sensitive data from the backend database, such as customer information, pricing, or proprietary business data, without altering data or causing denial of service. Although no known exploits are currently observed in the wild, the ease of exploitation combined with network accessibility and low privilege requirements makes this a critical issue for WooCommerce sites using this plugin. The lack of available patches at the time of publication increases the urgency for mitigation.

For European organizations operating e-commerce platforms using WooCommerce with the Perfect Brands plugin, this vulnerability poses a significant risk to customer data confidentiality and business information. Successful exploitation could lead to unauthorized disclosure of personal data, potentially violating GDPR requirements and resulting in regulatory penalties and reputational damage. The exposure of sensitive commercial data could also undermine competitive advantage. Since WooCommerce is widely used across Europe, especially by small and medium-sized enterprises (SMEs) in retail sectors, the impact could be widespread. Attackers could leverage this vulnerability to conduct targeted data exfiltration campaigns or prepare for further attacks by gathering intelligence. The limited impact on data integrity and availability reduces the risk of direct sabotage or service disruption, but the confidentiality breach alone is critical given the regulatory environment in Europe.

Immediate mitigation steps include disabling or uninstalling the Perfect Brands for WooCommerce plugin until a vendor patch is released. Organizations should monitor vendor communications for updates and apply patches promptly once available. As a temporary workaround, web application firewalls (WAFs) with SQL injection detection and prevention rules should be deployed or updated to specifically block malicious payloads targeting this plugin. Conduct thorough input validation and sanitization on all user inputs interacting with the plugin if custom code modifications are feasible. Additionally, restrict access to the WooCommerce administrative interface and plugin endpoints to trusted IP addresses where possible, reducing the attack surface. Regularly audit logs for suspicious SQL query patterns and anomalous database access. Organizations should also review and reinforce their data protection policies to ensure rapid response in case of data leakage.
