Description
CVE-2026-57112 is a high-severity vulnerability in MervinPraison's PraisonAI multi-agent system affecting versions from 0.6.0 up to but not including 1.6.59 and 3.10.0 up to but not including 4.6.59. The issue arises because the legacy SSE wrapper mounts SseServerTransport on /sse and /messages/ endpoints without enforcing Host, Origin, or authentication checks. This allows a malicious website to perform DNS rebinding attacks to enumerate and invoke registered tools with the server user's privileges. An initial fix was released in versions 1.6.59 and 4.6.59.
