CVE-2026-59295

Name of the Vulnerable Software and Affected Versions Apache HttpAsyncClient versions 4.x Apache HttpAsyncClient versions 5.x

Description Usage of Apache HttpAsyncClient via MicrometerHttpClientInterceptor can lead to unbounded memory leaks when asynchronous requests fail before a response is received, such as during connection resets or timeouts. The tracking state for these failed requests remains in memory indefinitely, which can result in heap exhaustion and OutOfMemoryError crashes.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
