Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion.
