CVE-2025-58615 is a Server-Side Request Forgery (SSRF) vulnerability identified in the WordPress plugin WP Bannerize Pro developed by gfazioli. SSRF vulnerabilities occur when an attacker can manipulate a server to make HTTP requests to arbitrary domains or internal systems, potentially bypassing network access controls. In this case, the vulnerability affects all versions of WP Bannerize Pro up to and including version 1.10.0. The vulnerability allows an attacker with high privileges (PR:H) and no user interaction (UI:N) to coerce the server hosting the plugin to send crafted requests to internal or external resources. The CVSS v3.1 base score is 4.4 (medium severity), reflecting that exploitation requires high privileges and has a high attack complexity. The impact includes limited confidentiality and integrity loss but no availability impact. Specifically, an attacker could use the SSRF to access internal services that are not normally exposed externally, potentially extracting sensitive information or manipulating internal APIs. The vulnerability is scoped (S:C), meaning the impact crosses security boundaries within the system. No known exploits are currently reported in the wild, and no patches have been linked yet. Given the plugin's role in managing banner advertisements on WordPress sites, the SSRF could be leveraged as part of a broader attack chain, especially in environments where the plugin is installed with elevated privileges or integrated with sensitive internal services.

For European organizations, the impact of this SSRF vulnerability depends on the deployment of WP Bannerize Pro within their WordPress environments. Organizations using this plugin, particularly those with complex internal networks or sensitive internal services accessible only from the web server, face risks of internal resource exposure. Attackers exploiting this vulnerability could access internal APIs, metadata services, or other protected resources, potentially leading to data leakage or further compromise. Although the CVSS score is medium, the scoped nature of the vulnerability means that if combined with other vulnerabilities or misconfigurations, it could facilitate privilege escalation or lateral movement within the network. This is particularly concerning for sectors with strict data protection requirements such as finance, healthcare, and government institutions in Europe. Additionally, the lack of a patch at the time of publication means organizations must rely on mitigation strategies to reduce risk. The requirement for high privileges to exploit limits the threat to attackers who have already compromised an account or system, but insider threats or chained attacks remain a concern.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Restrict access to the WordPress admin panel and plugin management to trusted administrators only, minimizing the risk of privilege abuse. 2) Employ network segmentation and firewall rules to limit the WordPress server's ability to make outbound HTTP requests to internal services that are not necessary for normal operation, effectively reducing the SSRF attack surface. 3) Monitor and log outbound HTTP requests from the WordPress server to detect unusual or unauthorized request patterns indicative of SSRF exploitation attempts. 4) Consider temporarily disabling or uninstalling WP Bannerize Pro if it is not essential, until a patch is available. 5) Use Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SSRF payloads targeting the plugin. 6) Keep WordPress core and all plugins updated and subscribe to vendor advisories for timely patch deployment once available. 7) Conduct internal audits to identify any sensitive internal services accessible from the WordPress server and apply additional access controls or authentication mechanisms to those services.
