Cvss 3 Severity Score

In GNOME Shell through 45.7, a portal helper can be launched automatically (without user confirmation) based on network responses provided by an adversary (e.g., an adversary who controls the local Wi-Fi network), and subsequently loads untrusted JavaScript code, which may lead to resource consumption or other impacts depending on the JavaScript code's behavior.

Notes

mdeslaur

See 3408 MR, ideally in Ubuntu we would switch to disabling the portal helper and use the user's default browser instead of using the embedded gtkwebkit browser to improve security. Need to test properly and make sure this works with our default browsers.
