CVE-2026-67424: CWE-918: Server-Side Request Forgery (SSRF) in flytohub flyto-core
Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.7, the HTTP modules http.get, http.request, and http.batch in src/core/modules/atomic/http/get.py, src/core/modules/atomic/http/request.py, and src/core/modules/atomic/http/batch.py validate only the initial URL, then follow redirects with allow_redirects=True and without per-hop Location revalidation, allowing a public URL to redirect into internal address space and return the internal response body. This issue is fixed in version 2.26.7.
AI Analysis
Technical Summary
flytohub flyto-core versions before 2.26.7 contain an SSRF vulnerability (CWE-918) in the HTTP modules http.get, http.request, and http.batch. These modules validate only the initial URL but follow HTTP redirects with allow_redirects=True without per-hop Location revalidation. This behavior allows a public URL to redirect into internal address space, enabling an attacker to retrieve internal response bodies. The vulnerability is addressed in flyto-core 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 requests to internal network resources. This can lead to disclosure of sensitive internal information (confidentiality impact is high), with limited integrity impact and no availability impact. The vulnerability has a CVSS 3.1 score of 8.5, indicating high severity.
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 vendor advisory content is provided to indicate alternative mitigations or temporary fixes.
