What is CVE-2020-1195?
CVE-2020-1195 is a low-severity path traversal vulnerability in Microsoft Edge, published on 21 May 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
An elevation of privilege vulnerability exists in Microsoft Edge (Chromium-based) when the Feedback extension improperly validates input. An attacker who successfully exploited this vulnerability could write files to arbitrary locations and gain elevated privileges. The vulnerability by itself does not allow arbitrary code to run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (for example a remote code execution vulnerability and another elevation of privilege vulnerability) to take advantage of the elevated privileges when running. The security update addresses the vulnerability by modifying how Microsoft Edge (Chromium-based) Feedback extension validates files.
