CVE-2020-14954
When a server sends a "begin TLS" response, the client reads additional data (e.g., from a man-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection."
MEDIUM 5.9EPSS 2.29%
Does this matter?
Lower severity and a low EPSS score (2.29%). Track it; it rarely justifies an emergency change on its own.
Description
