CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to disclose sensitive information and execute arbitrary script in the context of other open tabs.

The vulnerability exists due to improper access control in the Browser Relay /cdp WebSocket endpoint when handling browser-initiated loopback WebSocket connections. A remote attacker can connect to the local relay from a website and use Chrome DevTools Protocol messages to disclose sensitive information and execute arbitrary script in the context of other open tabs.

Exploitation requires the Browser Relay extension to be installed and active, and the victim must visit an untrusted site.
