CVE-2024-28120: Codeium

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

codeium-chrome is an open source code completion plugin for the chrome web browser. The service worker of the codeium-chrome extension doesn't check the sender when receiving an external message. This allows an attacker to host a website that will steal the user's Codeium api-key, and thus impersonate the user on the backend autocomplete server. This issue has not been addressed. Users are advised to monitor the usage of their API key.
