mcp-spring-webflux is vulnerable to Denial of Service (DoS)
75
High Risk
This Affects:
mcp-spring-webfluxTL;DR
mcp-spring-webflux and mcp-spring-webmvc retain MCP Streamable HTTP sessions with no cap, and authentication is not required by default. A remote client can create sessions until memory is exhausted. Legitimate clients then lose the service. The patch bounds the number of retained sessions.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and the MCP Streamable HTTP server transport is exposed without authentication.

How to fix this
Upgrade the org.springframework.ai:mcp-spring-webflux and/or the org.springframework.ai:mcp-spring-webmvc library to the patch version.
