CVE-2025-6515 (GCVE-0-2025-6515)
Vulnerability from cvelistv5 – Published: 2025-10-20 16:13 – Updated: 2025-10-20 16:33

Title
Reuse of session IDs in oatpp-mcp leads to session hijacking and prompt hijacking by remote attackers
Summary
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 from the oatpp-mcp server.
Severity
6.8 (Medium)
