micrometer-core is vulnerable to Denial of Service (DoS)
59
Medium Risk
This Affects:
micrometer-coreTL;DR
micrometer-core MicrometerHttpClientInterceptor never removes tracking state when an async HTTP request fails before a response, such as on connection reset or timeout. Sustained failures leak heap until the application crashes. This requires Micrometer instrumentation of Apache HttpAsyncClient 4.x or 5.x. The patch releases interceptor state on pre-response failures.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and Apache HttpAsyncClient is instrumented with MicrometerHttpClientInterceptor.
Background info
micrometer-core is vulnerable to Denial of Service (DoS) in versions 0.0.1 - 1.16.6 and 1.17.0 - 1.17.0.
How to fix this
Upgrade the io.micrometer:micrometer-core library to the patch version.
