CVE-2026-67428: CWE-918: Server-Side Request Forgery (SSRF) in flytohub flyto-core
CVE-2026-67428 is a Server-Side Request Forgery (SSRF) vulnerability in flytohub's flyto-core execution kernel for automation and AI-agent workflows. Versions prior to 2.26.7 allow HTTP-emitting modules to fetch URLs controlled by an attacker without proper validation, enabling SSRF attacks against internal or metadata endpoints. This vulnerability affects multiple modules including HTTP request handlers and notification senders. The issue is fixed in version 2.26.7.
AI Analysis
Technical Summary
Flyto-core versions before 2.26.7 contain an SSRF vulnerability (CWE-918) due to insufficient validation of URLs fetched by various HTTP-emitting modules such as src/core/modules/third_party/developer/http/requests.py, core.api.http_get, core.api.http_post, graphql.query, graphql.mutation, and notification modules for Slack, Discord, and Teams. These modules do not use the validate_url_with_env_config function, allowing attacker-controlled URLs to be fetched, potentially targeting internal or metadata endpoints. The vulnerability is resolved in version 2.26.7.
Potential Impact
An attacker with at least low privileges can exploit this SSRF vulnerability to cause the server to make unauthorized HTTP requests to internal or metadata endpoints. The CVSS score of 8.5 indicates high severity with high confidentiality impact, limited integrity impact, and no availability impact. This could lead to unauthorized information disclosure from internal services.
Mitigation Recommendations
A fix is available in flyto-core version 2.26.7. Users should upgrade to version 2.26.7 or later to remediate this vulnerability. No additional mitigation guidance is provided or required beyond applying the official fix.
