Summary

CVE-2026-5016 is a medium-severity SSRF (CWE-918) vulnerability. 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 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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.

CVE-2026-5016 is a server-side request forgery (SSRF) vulnerability affecting elecV2 and elecV2P versions up to 3.8.3. The issue resides in the eAxios function within the /mock file of the URL Handler component, where manipulation of the req argument enables the forgery. Assigned CWE-918, it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and lack of prerequisites.

Remote attackers require no privileges or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling attackers to forge requests from the server to unintended destinations, such as internal services. A public exploit is available, increasing the risk of widespread use.

Advisories from VulDB and the project's GitHub repository note that the issue was reported early via elecV2/elecV2P issue #202, but the maintainers have not yet responded or released patches. No specific mitigations are detailed in the references; practitioners should monitor the GitHub repository for updates and consider network segmentation or disabling the affected component until remediation.

The exploit's public availability suggests potential for active exploitation, though no confirmed real-world incidents are reported in the provided data.

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.
