CVE-2026-67425: Flytohub Flyto-Core

High severity, CVSS 8.6. EPSS: 0.6% chance of exploitation in the next 30 days.

Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.6, llm.chat reads provider keys such as OPENAI_API_KEY and ANTHROPIC_API_KEY from the environment and sends them in the Authorization: Bearer header to caller-controlled base_url, allowing an attacker to receive the operator's key on a public host that passes the SSRF guard. This issue is fixed in version 2.26.6.

Affected products

• Flytohub Flyto-Core: before 2.26.6 (fixed in 2.26.6)
