CVE-2024-4109 (opens in a new tab)Amendment
This was deemed not a vulnerability.
Overview
io.undertow:undertow-core is a Java web server based on non-blocking IO.
Affected versions of this package are vulnerable to Information Exposure via the reuse of HTTP/2 request headers. An attacker can access sensitive information from previous requests by exploiting the incorrect reuse of header values across different streams on the same connection.
Note: The CVE for this vulnerability has been rejected because multiple invocations of the same HpackDecoder from different threads are required for the vulnerability but such concurrent accesses are not possible, so the issue is not exploitable.
