CVE-2025-6515

The CVE concerns oatpp-mcp’s MCP SSE endpoint, where a session ID is derived from an instance pointer instead of a unique, cryptographically secure value. This enables a network attacker with access to the oatpp-mcp server to predict/guess future session IDs, hijack legitimate MCP sessions, and c...

CVE-2025-6515 Reuse of session IDs in oatpp-mcp leads to session hijacking and prompt hijacking by remote attackers

The MCP SSE endpoint in oatpp-mcp returns an instance pointer as the session ID, which is not unique nor cryptographically secure. This allows network attackers with access to the oatpp-mcp server to guess future session IDs and hijack legitimate client MCP sessions, returning malicious responses...
