TL;DR

spring-cloud-function-context composition lookup can overwrite the base function registration. An attacker who can influence composition lookup may replace the intended function with another. Later invocations then run the poisoned function. The patch isolates composition lookup from the base function mapping.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and function composition lookup is reachable with untrusted composition names.
