CVE-2025-13872 is a Blind Server-Side Request Forgery (SSRF) vulnerability identified in ObjectPlanet Opinio version 7.26 rev12562, a web-based survey and polling platform. The flaw exists in the survey-import feature, which improperly validates or sanitizes input URLs used during the import process. An attacker with high privileges on the system can craft malicious import requests that cause the server to issue HTTP GET requests to arbitrary destinations. This SSRF is 'blind' because the attacker does not receive direct response data from the targeted requests, limiting immediate exploitation but still enabling indirect reconnaissance or interaction with internal services. The vulnerability has been assigned a CVSS 4.0 score of 2.1, reflecting its low severity due to the high attack complexity, requirement for privileged access, and lack of user interaction. No public exploits or active exploitation have been reported to date. Despite the low score, SSRF vulnerabilities can be leveraged in chained attacks to pivot into internal networks, access metadata services, or bypass firewalls if the server has broad network access. The lack of available patches at the time of disclosure means organizations must rely on network-level mitigations and monitoring until vendor fixes are released. This vulnerability is cataloged under CWE-918, which covers SSRF issues where servers are tricked into making unintended requests. The affected product, ObjectPlanet Opinio, is used primarily in survey and opinion polling contexts, often by market research firms and public institutions.

For European organizations, the impact of CVE-2025-13872 is generally low but context-dependent. Since exploitation requires high privileges on the server, the vulnerability does not directly enable remote attackers to gain initial access. However, once an attacker has such access, they can use SSRF to perform internal network reconnaissance, potentially accessing sensitive internal services or data not exposed externally. This can lead to information disclosure or facilitate lateral movement within the network. Organizations handling sensitive survey data or operating in regulated sectors (e.g., government polling agencies, market research firms) could face reputational damage or compliance issues if internal data is exposed. The vulnerability could also be used to bypass network segmentation or firewall rules if the server can reach otherwise restricted endpoints. Given the low CVSS score and lack of known exploits, immediate risk is limited, but the threat should not be ignored in environments where internal network security is critical. European entities with extensive use of ObjectPlanet Opinio in critical functions may face higher risk exposure.

1. Monitor and restrict outbound HTTP requests from servers running ObjectPlanet Opinio, especially those handling survey imports, to only trusted destinations. 2. Implement network egress filtering and firewall rules to prevent unauthorized internal or external requests initiated by the application server. 3. Enforce strict access controls and minimize privileges for users who can perform survey imports to reduce the risk of exploitation. 4. Conduct regular audits and logging of import feature usage to detect anomalous or suspicious request patterns indicative of SSRF attempts. 5. Engage with ObjectPlanet for timely patches or updates addressing this vulnerability and apply them promptly once available. 6. Consider deploying web application firewalls (WAFs) with SSRF detection capabilities to block malicious crafted requests. 7. Segment internal networks to limit the impact of SSRF-induced requests reaching sensitive internal services. 8. Educate administrators and developers about SSRF risks and secure coding practices to prevent similar issues in future versions.
