Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 87.0.4280.141

Description The issue is related to a use after free in drag and drop functionality, potentially allowing a remote attacker who has compromised the renderer process to perform a sandbox escape via a crafted HTML page.
