Does this matter?

Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.

Description

A prior update that raised a bundled HTTP client library to a version remediating known vulnerabilities was later reverted, reintroducing the earlier, vulnerable version into a log-processing component. The only code path in that component using the library issues a request to a single fixed, trusted vendor URL at initialization and does not process attacker-controlled input through the library, limiting practical exploitability of the reintroduced version in this context.
