CVE-2026-56769: Authenticated SSRF in Huly Platform Import Endpoint

Technical summary

CVE-2026-56769 is an authenticated SSRF vulnerability (CWE-918) in the /import endpoint of Huly Platform's front pod. The flaw allows authenticated users to provide attacker-controlled URLs that the server will fetch server-side, bypassing network access controls. An attacker can map internal service discovery, exfiltrate service responses, and potentially extract or replay credentials embedded in responses. The vulnerability affects all versions through 0.7.423 and has been patched in commit 68cbf8a. The CVSS 3.1 score of 8.5 (HIGH) reflects high confidentiality impact, low integrity impact, and scope change due to network-adjacent attack surface.

Business impact

This vulnerability enables authenticated insiders or compromised accounts to conduct reconnaissance and lateral movement within your infrastructure. An attacker can discover and interact with internal services (databases, admin panels, cloud metadata endpoints, message queues) that are not directly internet-accessible, potentially stealing credentials, configuration data, or triggering unauthorized operations. Organizations with microservice or containerized architectures are at particular risk if internal service communication relies on implicit network trust. Remediation requires immediate patching to prevent credential theft and unauthorized backend system compromise.

Affected systems

Huly Platform deployments running version 0.7.423 and earlier are affected. The vulnerability resides in the front pod's /import endpoint, affecting all instances regardless of deployment architecture (cloud, on-premises, containerized). Organizations using Huly for workspace collaboration with backend microservices or cloud integrations should prioritize assessment. The fixed commit 68cbf8a in the Huly repository should be verified against your release notes and patch timeline.

Exploitability

Exploitation requires valid workspace authentication credentials—the attacker must have an active user account within a Huly workspace. The attack surface is internal; no unauthenticated remote code execution or public exploit is required. Once authenticated, exploitation is trivial: an attacker simply crafts a request to the /import endpoint with a malicious URL targeting internal services (e.g., http://localhost:6379, http://internal-db:5432, http://169.254.169.254/latest/meta-data/). The server will fetch the URL and return or log the response, leaking sensitive data. No public KEV designation or active widespread exploitation has been reported as of the modification date.

Remediation

Upgrade Huly Platform to a version containing commit 68cbf8a or later. Before patching, implement network-level controls: restrict egress from Huly front pods to only required external services, block access to internal IP ranges (127.0.0.1, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 169.254.0.0/16) at the pod/container network policy layer, and disable or heavily restrict the /import endpoint if not actively used. Review workspace user access permissions and consider disabling import functionality for non-administrative users pending patch deployment.

Patch guidance

Apply the patch from commit 68cbf8a or upgrade to the next stable release that includes this fix. Verify the commit hash in your release notes or Git history. Coordinate a controlled rollout to validate no import workflows are broken in your environment. Test the /import endpoint with legitimate use cases after patching. For organizations unable to patch immediately, implement the network controls outlined in remediation_summary and monitor for suspicious import requests.

Detection guidance

Monitor logs for POST requests to the /import endpoint originating from non-administrative or unexpected user accounts. Flag imports requesting URLs matching internal IP ranges, localhost, cloud metadata endpoints (169.254.169.254), or DNS names resolving to private IPs. Inspect import request payloads and responses for evidence of service discovery or credential exfiltration. Set up alerts for HTTP 200/500 responses from /import that contain database connection strings, AWS credentials, or API keys. Network-layer detection: log outbound connections from Huly front pods to internal IP ranges and alert on anomalies.

Why prioritize this

A CVSS score of 8.5 and HIGH severity designation warrant immediate priority, particularly for organizations with sensitive internal infrastructure adjacent to Huly deployments. The vulnerability bridges the authentication boundary to backend systems, enabling lateral movement and credential theft. Although authentication is required, the barrier is low for insider threats or compromised accounts. The availability of a confirmed fix (commit 68cbf8a) makes remediation actionable, justifying urgent patching within 24–48 hours.

Risk score, explained

The score of 8.5 reflects: (1) HIGH confidentiality impact—internal service responses and credentials can be exfiltrated; (2) LOW integrity impact—responses may be logged or replayed, but direct system modification is not guaranteed; (3) SCOPE CHANGE—the vulnerability allows an authenticated user to impact backend systems beyond the front pod; (4) LOW attack complexity and network accessibility; (5) LOW privilege requirement (authenticated user, not administrator). Remediation lowers risk to baseline once patched.
