CVE intelligence and bounded remediation

CVE-2024-28120 — codeium-chrome is an open source code completion plugin for the chrome web browser

High CVSS 7.5

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.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
