{"id":"CVE-2026-115750","summary":"mcp-from-openapi from 2.5.0 before 2.9.0 Credential Leak via Cross-Origin Redirects","details":"mcp-from-openapi from 2.5.0 before 2.9.0 contains a credential exposure vulnerability that allows attackers to capture Authorization and Cookie headers because safeFetch() forwards them on cross-origin redirects.
