CVE-2026-31317 is a high-severity SSRF (CWE-918) vulnerability. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 38th 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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-31317 is a Server-Side Request Forgery (SSRF) vulnerability (CWE-918) in CraftQL versions 1.3.7 and prior. The flaw exists in the file vendor/markhuot/craftql/src/Listeners/GetAssetsFieldSchema.php and enables attackers to execute arbitrary code. It has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high severity due to network accessibility, low attack complexity, and no privileges required.
Unauthenticated remote attackers can exploit this vulnerability without user interaction by sending crafted requests to a vulnerable CraftQL instance. Exploitation leads to arbitrary code execution, resulting in high confidentiality impact as attackers can access sensitive data or internal resources via SSRF.
Mitigation details are available in related references, including the official CraftQL repository at https://github.com/markhuot/craftql and a proof-of-concept repository at https://github.com/stormmmg/craftql_ssrf/, with additional documentation at https://github.com/stormmmg/craftql_ssrf/blob/master/craftql-ssrf-en/README_detail.md. The vulnerability was published on 2026-04-17T14:16:33.730.

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.

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.
