Summary
CVE-2025-31117 is a medium-severity SSRF (CWE-918) vulnerability in Open-Emr Openemr. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 40th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
OpenEMR, a free and open source electronic health records and medical practice management application, is affected by an out-of-band server-side request forgery vulnerability tracked as CVE-2025-31117. The flaw, classified under CWE-918, allows an attacker to force the server to issue unauthorized requests to external or internal resources; unlike classic SSRF, it does not return a direct response but can still be leveraged through DNS or HTTP callbacks.
An unauthenticated remote attacker can exploit the issue over the network to exfiltrate sensitive information by inducing the server to interact with attacker-controlled infrastructure, achieving limited confidentiality impact without requiring user interaction or elevated privileges.
The vulnerability is fixed in OpenEMR version 7.0.3.1, according to the project’s GitHub security advisory and the associated commit that resolves the flaw. The EPSS score remains low, with a current value of 0.0115 and a peak of 0.0185.

Mitigating Controls (NIST 800-53 r5) AI
Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.
Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.
Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure development practices directly include input validation and destination allow-listing that prevent SSRF.
Runtime monitoring of web applications and services can detect anomalous outbound requests indicative of SSRF.
Vulnerability identification processes can discover and record SSRF flaws in web applications.
Network segmentation and egress controls can limit the damage from successful SSRF requests.
