CVE-2026-115750— mcp-from-openapi from 2.5.0 before 2.9.0 Credential Leak via Cross-Origin Redirects

Quick assessment

Affected
agentfront mcp-from-openapi
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

mcp-from-openapi 在 2.5.0 至 2.9.0（不含）版本中存在凭证泄露漏洞。由于 safeFetch() 函数在跨域重定向时会转发 Authorization 和 Cookie 请求头，攻击者可借此捕获这些敏感信息。若攻击者能够控制规范（spec）主机或滥用开放重定向漏洞，他们可将 fromURL() 发起的规范请求重定向至其控制的域名，从而窃取 Bearer 令牌或 Cookie。
