CVE-2025-47483 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Easy Replace Image plugin developed by Iulia Cazan. 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. This specific vulnerability affects Easy Replace Image versions up to 3.5.0. The CVSS 3.1 base score is 4.9, indicating a medium severity level. The vector string (AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N) reveals that the attack can be performed remotely over the network (AV:N), requires a low level of privileges (PR:L), but has high attack complexity (AC:H), and does not require user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), with no impact on availability (A:N). The vulnerability allows an attacker with low privileges to coerce the server into making unauthorized requests, potentially accessing internal or protected resources, or causing information disclosure. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is recognized by CISA and has been published recently, indicating it is a new and emerging threat. The lack of patches and the medium complexity of exploitation suggest that while exploitation is not trivial, it remains a concern for organizations using this plugin, especially if it is exposed to untrusted users or the internet.

For European organizations, the SSRF vulnerability in Easy Replace Image could lead to unauthorized internal network scanning, data leakage, or access to internal services that are not otherwise exposed externally. This can be particularly impactful for organizations that use this plugin in web environments connected to sensitive internal systems or cloud services. Confidentiality and integrity impacts, although rated low, could still enable attackers to gather information useful for further attacks or pivoting within the network. The medium attack complexity and requirement for low privileges mean that insider threats or compromised low-privilege accounts could exploit this vulnerability. Given the plugin's role in image replacement, it may be integrated into content management systems or websites, potentially exposing customer or business data. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time. European organizations with strict data protection regulations (e.g., GDPR) must consider the risk of data exposure and unauthorized access resulting from SSRF attacks.

1. Immediate mitigation should include restricting access to the Easy Replace Image plugin to trusted users only, minimizing exposure to untrusted or anonymous users. 2. Network-level controls should be implemented to prevent the web server from making arbitrary outbound requests, especially to internal IP ranges or sensitive endpoints. 3. Employ web application firewalls (WAFs) with rules designed to detect and block SSRF patterns, such as unusual URL parameters or requests targeting internal IP addresses. 4. Monitor logs for unusual outbound requests initiated by the plugin or web server processes. 5. Until an official patch is released, consider disabling or removing the Easy Replace Image plugin if it is not essential. 6. If the plugin is critical, implement input validation and sanitization on any user-supplied URLs or parameters used by the plugin to prevent manipulation. 7. Keep abreast of vendor announcements for patches or updates addressing this vulnerability and apply them promptly once available. 8. Conduct internal penetration testing focusing on SSRF vectors to identify any other potential weaknesses in the environment.
