The vulnerability identified as CVE-2025-63010 is a Server-Side Request Forgery (SSRF) issue found in ThemesInflow's Hercules Core product, affecting all versions up to 7.4. SSRF vulnerabilities occur when an attacker can manipulate a server to send HTTP requests to arbitrary domains or internal network resources, which the attacker cannot directly access. In this case, the vulnerability allows an attacker to exploit the server's request functionality to reach internal services, potentially bypassing firewall rules or network segmentation. This can lead to unauthorized access to sensitive internal endpoints, such as metadata services, internal APIs, or administrative interfaces. The absence of a CVSS score and known exploits suggests this is a newly disclosed vulnerability, but the risk remains significant due to the nature of SSRF attacks. The lack of patch information indicates that users must rely on configuration and network-level mitigations until an official fix is released. The vulnerability's impact depends on the server's network environment and the sensitivity of accessible internal resources. Attackers might leverage SSRF to perform reconnaissance, extract sensitive data, or pivot deeper into the network. The vulnerability affects a widely used product in web environments, increasing the potential attack surface.

For European organizations, the SSRF vulnerability in ThemesInflow Hercules Core could lead to unauthorized internal network access, data leakage, and potential lateral movement within corporate networks. Organizations that deploy Hercules Core in environments with sensitive internal services or cloud metadata endpoints are at higher risk. Exploitation could compromise confidentiality by exposing internal data, integrity by allowing unauthorized actions on internal services, and availability if critical internal services are disrupted. The impact is amplified in sectors such as finance, healthcare, and government, where internal network security is paramount. Additionally, organizations using Hercules Core in multi-tenant or cloud environments may face risks of cross-tenant data exposure. The lack of patches increases the window of exposure, necessitating urgent mitigation. The vulnerability could also facilitate advanced persistent threat (APT) activities by enabling stealthy internal reconnaissance. Overall, the threat poses a significant risk to European entities relying on this software, especially those with complex internal network architectures.

1. Immediately audit all deployments of ThemesInflow Hercules Core to identify affected versions (<=7.4). 2. Implement strict input validation and sanitization on any user-controllable parameters that trigger server-side requests to prevent injection of malicious URLs. 3. Restrict outbound HTTP requests from the application server to only trusted external endpoints using firewall rules or network segmentation. 4. Employ network-level controls such as egress filtering and internal service authentication to limit access to sensitive internal resources. 5. Monitor logs and network traffic for unusual or unexpected server-side requests indicative of SSRF exploitation attempts. 6. Engage with ThemesInflow for official patches or updates and apply them promptly once available. 7. Consider deploying Web Application Firewalls (WAFs) with SSRF detection capabilities to block malicious requests. 8. Educate development and operations teams about SSRF risks and secure coding practices to prevent similar vulnerabilities. 9. Use internal service authentication mechanisms (e.g., tokens, mutual TLS) to prevent unauthorized access even if SSRF is exploited. 10. Conduct penetration testing focusing on SSRF vectors to validate the effectiveness of mitigations.
