CVE-2026-114362: HarnessRouter server-side request forgery in Targets endpoint

CVE-2026-114362 · Severity: medium · CVSS 6.3 · Published 2026-10-21

HarnessRouter is a self-hosted unified interface for running code generation and AI models through a common API. A flaw in the Targets Test Endpoint allows remote attackers to manipulate a base_url parameter, causing the server to make requests to attacker-controlled destinations. This could lead to unauthorized access to internal systems, data exfiltration, or further compromise of the server infrastructure.

Technical details

A server-side request forgery (SSRF) vulnerability exists in gateway/app.py's handling of the base_url argument in the Targets Test Endpoint. The vulnerability can be exploited remotely without authentication by sending a maliciously crafted request with a manipulated base_url parameter. Attackers can use this to probe internal networks, access cloud metadata services, or interact with backend systems unavailable externally.
