GHSA-V7HR-HGG3-VV6Q

Vulnerability from github – Published: 2026-08-24 12:31 – Updated: 2026-08-24 12:31

Details

Micrometer-instrumented Apache HttpAsyncClient (4.x or 5.x) usage via MicrometerHttpClientInterceptor can leak memory unboundedly when asynchronous requests fail before receiving a response (e.g. connection resets or timeouts). Tracking state for these requests remains in memory indefinitely, and sustained failures lead to heap exhaustion and OutOfMemoryError crashes.

Severity

5.9 (Medium)


                  
                    CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
