CVE-2022-41971
An attacker would be able to see videos on a call in a public conversation after being removed from that conversation, provided that they were removed while being in the call.
Does this matter?
Lower severity and a low EPSS score (0.79%). Track it; it rarely justifies an emergency change on its own.
