CVE-2022-45872Network attack vector

Unspecified impact via mishandled DECRQSS response

Published Nov 23, 2022 · Updated Apr 25, 2025

Improper input validation in iTerm2 before 3.4.18 allows remote attackers to cause unspecified impact via a DECRQSS response. The vendor says the DECRQSS response was changed to close a security hole but has not published the faulty parser operation or malformed input condition. Reachability requires an attacker-controlled response, while public vendor material does not identify the resulting consequence.
