What is CVE-2025-27155?

The Pinecone Simulator, which serves as an experimental overlay routing protocol suite for P2P Matrix demos, is susceptible to a stored cross-site scripting issue. This vulnerability arises from inadequate handling of input, allowing an attacker to inject malicious scripts that could be executed in the context of another user's browser session. Although the payload storage is transient and is cleared upon restarting pineconesim, the potential for exploitation remains a significant concern during active sessions.
