CVE-2025-49418 is a Server-Side Request Forgery (SSRF) vulnerability identified in the TeconceTheme Allmart product, affecting versions up to 1.0.0. SSRF vulnerabilities occur when an attacker can manipulate a server to make HTTP requests to arbitrary domains or internal systems, potentially bypassing firewall restrictions and accessing internal resources not directly exposed to the internet. In this case, the vulnerability allows unauthenticated, remote attackers to induce the Allmart theme server to send crafted requests, which can lead to information disclosure and integrity impacts. The CVSS 3.1 base score of 7.2 reflects a high severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), scope changed (S:C), and impacts on confidentiality and integrity but not availability (C:L/I:L/A:N). The scope change means the vulnerability affects components beyond the initially vulnerable component, increasing the potential impact. Although no known exploits are currently reported in the wild, the vulnerability's nature and ease of exploitation make it a significant risk. The lack of available patches at the time of publication increases the urgency for mitigation. SSRF can be leveraged to access internal services, metadata endpoints, or other sensitive resources, potentially leading to further compromise or data leakage within the affected environment.

For European organizations using the TeconceTheme Allmart product, this SSRF vulnerability poses a significant risk to internal network security and data confidentiality. Attackers exploiting this flaw could access internal APIs, cloud metadata services, or other protected resources, potentially leading to unauthorized data access or lateral movement within the network. Given the scope change, the vulnerability could impact multiple components or services beyond the theme itself, amplifying the risk. Organizations in sectors with sensitive data, such as finance, healthcare, or government, could face regulatory and reputational damage if internal data is exposed. The lack of authentication and user interaction requirements means attackers can exploit this vulnerability remotely and without user involvement, increasing the likelihood of automated attacks. Additionally, the absence of known exploits currently does not preclude rapid development of exploit code, especially given the public disclosure. European organizations relying on this theme for e-commerce or content management should be vigilant, as SSRF can be a stepping stone to more severe attacks including server compromise or data exfiltration.

1. Immediate mitigation should include disabling or restricting any functionality in the TeconceTheme Allmart product that allows server-side HTTP requests until a patch is available. 2. Implement strict input validation and sanitization on any user-controllable parameters that influence server requests, ensuring only allowed URLs or domains can be accessed. 3. Employ network-level controls such as firewall rules or web application firewalls (WAFs) to block outgoing requests from the web server to internal IP ranges or sensitive endpoints, limiting SSRF exploitation scope. 4. Monitor logs for unusual outbound HTTP requests or patterns indicative of SSRF attempts. 5. Segregate internal services and metadata endpoints from the web-facing servers to reduce exposure. 6. Once a patch or update is released by TeconceTheme, prioritize timely application of the fix. 7. Conduct security assessments and penetration testing focused on SSRF vectors to identify and remediate any related weaknesses. 8. Educate development and operations teams about SSRF risks and secure coding practices to prevent similar vulnerabilities in the future.
