CVE-2025-49418 is a Server-Side Request Forgery (SSRF) vulnerability identified in the TeconceTheme Allmart product, a theme presumably used in web applications or content management systems. SSRF vulnerabilities occur when an attacker can abuse a server's functionality to send crafted requests from the server to internal or external systems that the server can access. This vulnerability allows an unauthenticated attacker to induce the server to make arbitrary HTTP requests without user interaction, potentially bypassing network restrictions and accessing internal resources. The vulnerability affects Allmart versions up to 1.0.0, though exact affected versions are unspecified. The CVSS v3.1 base score is 7.2 (high severity), with vector AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N, indicating network attack vector, low attack complexity, no privileges or user interaction required, and scope change. The impact includes partial confidentiality and integrity loss but no availability impact. The vulnerability could be exploited to access sensitive internal services, gather information, or perform further attacks such as SSRF-based port scanning or exploiting internal APIs. No known exploits are reported in the wild yet, and no patches are currently linked, indicating that mitigation may require vendor updates or configuration changes. The CWE-918 classification confirms the SSRF nature of the flaw. Given the scope change, exploitation could affect resources beyond the initially vulnerable component, increasing risk.

For European organizations using TeconceTheme Allmart, this SSRF vulnerability poses significant risks. Attackers could leverage the vulnerability to access internal network resources that are otherwise protected by firewalls, such as internal APIs, databases, or cloud metadata services, potentially leading to data leakage or further compromise. Confidentiality is partially impacted as attackers might retrieve sensitive information from internal systems. Integrity could be affected if the attacker uses SSRF to interact with internal services that allow modification of data. Although availability is not directly impacted, the indirect consequences of data breaches or lateral movement could disrupt operations. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, face heightened risks due to potential exposure of personal or sensitive data. The lack of authentication and user interaction requirements lowers the barrier for exploitation, increasing the threat level. European companies relying on this theme for e-commerce or content delivery may experience reputational damage and regulatory penalties if exploited.

Immediate mitigation steps include: 1) Restricting outbound HTTP requests from the web server hosting Allmart to only trusted destinations using firewall rules or network segmentation to limit SSRF impact. 2) Implementing input validation and sanitization on any user-supplied URLs or parameters that trigger server-side requests to ensure only allowed domains or IP ranges are reachable. 3) Monitoring logs for unusual outbound request patterns indicative of SSRF exploitation attempts. 4) Applying web application firewall (WAF) rules tailored to detect and block SSRF attack patterns targeting Allmart. 5) Contacting the vendor or theme provider for patches or updates addressing the vulnerability and applying them promptly once available. 6) If patching is delayed, consider disabling or restricting features in Allmart that perform server-side requests. 7) Conducting internal network scans to identify and secure sensitive services that could be targeted via SSRF. These targeted mitigations go beyond generic advice by focusing on network-level controls, input validation, and proactive monitoring specific to SSRF in the context of Allmart.
