CVE-2022-39246 is a medium-severity vulnerability affecting the Matrix Android SDK (matrix-android-sdk2) prior to version 1.5.1. It allows a malicious homeserver to craft messages appearing to originate from another user due to overly permissive key forwarding.

There is no evidence of active exploitation, public exploit code, or significant community discussion, though it has received some media coverage.
