What is CVE-2026-41710?

The vulnerability in Spring Retry allows an attacker to send numerous unique requests that overwhelm the application’s stateful retry cache. Once this cache reaches its limit, it prevents any further updates, leading to a failure in all subsequent stateful retries and circuit breaker operations. This condition can leave applications unable to process legitimate requests, significantly impacting performance and reliability. Version updates from 2.0.0 to 2.0.12 and 1.3.0 to 1.3.4 are particularly vulnerable.

Affected Version(s)

Spring Retry 2.0.0 < 2.0.12.1

Spring Retry 1.3.0 < 1.3.5

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
