CVE-2021-34425

Estado: ModificadaMedia (6.1)—

The Zoom Client for Meetings before version 5.7.3 (for Android, iOS, Linux, macOS, and Windows) contain a server side request forgery vulnerability in the chat\'s "link preview" functionality. In versions prior to 5.7.3, if a user were to enable the chat\'s "link preview" feature, a malicious actor could trick the user into potentially sending arbitrary HTTP GET requests to URLs that the actor cannot reach directly.
