Impact

Flyto2 Core is an execution kernel that powers automation and AI‑agent workflows. Prior to version 2.26.7, several HTTP‑emitting modules – such as requests, http_get, http_post, GraphQL, monitoring, communication, notification, AI vision, visual diff, and browser proxy modules – could request URLs supplied by callers without performing the validate_url_with_env_config check. This permits an attacker to supply a crafted URL and cause the process to contact internal or metadata endpoints, resulting in Server Side Request Forgery. The weakness is categorized as CWE‑918.

Affected Systems

The vulnerable product is Flytohub Flyto‑Core, all releases before 2.26.7. The vendor notes that the issue is fixed in v2.26.7, so deployments running 2.26.6 or older remain at risk.

Risk and Exploitability

The CVSS score of 8.5 indicates a high severity vulnerability. The EPSS score is below 1%, indicating a low current exploitation probability, and the vulnerability is not listed in CISA KEV. Based on the description, it is inferred that an attacker would need to supply a malicious URL through an exposed API endpoint to trigger the vulnerable modules. If the application can reach internal addresses, the SSRF could allow access to internal or metadata endpoints. No workaround is offered; the only fix is to apply the patch.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Flyto‑Core to version 2.26.7 or later.
  • If an upgrade is not immediately possible, block or restrict outbound HTTP requests from vulnerable modules to known safe domains or deny access to internal addresses.
  • Configure firewall or network segmentation rules to prevent the application from reaching internal metadata services.
