Bug report
Both the CVE-2024-5386 and CVE-2024-6778 directories contains a POC Chrome extension that is able to execute arbitrary JS on privileged WebUI pages. CVE-2024-5386 relies on a race condition and is fairly unreliable, while CVE-2024-6778 does not.
The sandbox-escape directory contains the full exploit chain, using CVE-2024-6778 to gain code execution in chrome://policy, which leads to a sandbox escape by setting the legacy browser support policies.
