Summary

CVE-2026-5607 is a low-severity SSRF (CWE-918) vulnerability. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 19th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

This vulnerability is AI-related — categorised as AI Agent Protocols and Integrations; in the Protocol-Specific Risks risk domain.

The strongest mitigations our analysis identified map to SC-7 (Boundary Protection) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

A security vulnerability has been detected in imprvhub mcp-browser-agent up to 0.8.0. This impacts the function CallToolRequestSchema of the file src/handlers.ts of the component URL Parameter Handler. The manipulation of the argument request.params.name/request.params.arguments leads to server-side request forgery. The attack…

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

SSRF in public-facing URL parameter handler directly enables remote exploitation of the application per T1190.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces validation of URL parameters (request.params.name/arguments) to reject SSRF payloads before they trigger outbound requests.

prevent

Boundary protection rules can explicitly deny or restrict the server process from initiating arbitrary outbound connections to internal or external targets.

prevent

Information flow policies can be configured to block unauthorized server-initiated requests originating from untrusted user-supplied parameters.
