CVE-2026-40989

A flaw was found in Spring Cloud Function. An attacker could send a specially crafted request that triggers infinite recursion in the routing layer. This can lead to an Out Of Memory OOM error, causing a Denial of Service DoS condition where the application becomes unresponsive...

Denial Of Service (DoS)

Spring Cloud Function is vulnerable to Denial of Service DoS. The vulnerability is due to insufficient restrictions on function registration within the Function Registry, allowing an attacker to register an unbounded number of functions and trigger excessive memory consumption, potentially...
