Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly validates untrusted inputs to the GetAssetsFieldSchema.php listener, preventing SSRF exploitation and subsequent arbitrary code execution.
Remediates the specific SSRF flaw in CraftQL v1.3.7 and prior by applying vendor patches or updates from the official repository.
Enforces boundary protections to monitor and restrict server-side requests to internal resources or localhost, mitigating SSRF impacts.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
SSRF flaw in public-facing CraftQL service permits unauthenticated remote attackers to achieve arbitrary code execution via crafted requests, directly enabling exploitation of internet-facing applications.
NVD Description
Craftql v1.3.7 and before is vulnerable to Server-Side Request Forgery (SSRF) which allows an attacker to execute arbitrary code via the vendor/markhuot/craftql/src/Listeners/GetAssetsFieldSchema.php file
Deeper analysisAI
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.
