Title
Micrometer Instrumentation of Apache HttpAsyncClient Denial of Service Vulnerability
Summary
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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
