Summary

CVE-2025-10096 is a low-severity SSRF (CWE-918) vulnerability in Sim Sim. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Network Service Discovery (T1046); ranked at the 17th 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.

Why these techniques?

SSRF vulnerability in public-facing API (/api/files/parse) enables initial access via exploitation of public-facing application (T1190), internal network service discovery by probing internal hosts/services (T1046), and use of the compromised server as an internal proxy (T1090.001).

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Validates the filePath argument in route.ts to reject untrusted or external URLs that enable SSRF.

AC-4 Information Flow Enforcement good match
prevent

Enforces information flow policies that restrict the server from issuing arbitrary outbound requests based on user-supplied paths.

SC-7 Boundary Protection partial match
prevent

Applies boundary filtering rules to block unauthorized outbound connections that would otherwise be triggered by the SSRF payload.
