⚠️ An unsuspecting HTML page can serve as a secret passage! A use-after-free vulnerability in Google Chrome's reader mode on Android prior to version 83.0.4103.61 lets a remote attacker potentially escape the sandbox. 🚧 Think of it like a hotel that forgot to remove a guest's access after they checked out — that former tenant could sneak back in and access restricted areas! An attacker who has compromised the renderer process could exploit this vulnerability to escape from the secure environment of the browser, potentially gaining access to sensitive data or system features that should be off-limits. The consequences could be severe, putting your privacy and security at risk!
