One-Click GitHub Dev Attack Lets Attackers Steal Full GitHub OAuth Tokens

Vulnerability: Attackers can steal full GitHub OAuth tokens via malicious VS Code extensions in GitHub.dev with one-click exploits.

Deep Analysis and Expert Commentary

The attack chain begins when a victim clicks a malicious link, triggering JavaScript in an untrusted webview to simulate Ctrl+Shift+P and open VS Code's Command Palette. The exploit then installs a weaponized extension from the workspace's .vscode/extensions folder, bypassing publisher checks. Once installed, the extension harvests the broad-scope OAuth token passed to GitHub.dev, which unlike repo-specific tokens, grants full read/write access to all victim repositories. This flaw stems from GitHub.dev's overly permissive token delegation and VS Code's failure to enforce webview isolation. Mitigations include disabling automatic GitHub.dev token passing, auditing local workspace extensions, and restricting webview JavaScript execution until patches are released.

Action Items

  • Disable automatic GitHub OAuth token delegation to GitHub.dev in account settings
  • Audit .vscode/extensions folders for unauthorized local workspace extensions
  • Implement network controls to block suspicious GitHub API requests from developer environments

Enforcing the First AS in BGP AS_PATHs

Vulnerability: Enforcing First AS verification in BGP routes mitigates hijacks by preventing forged AS_PATHs and misdirected traffic.

Deep Analysis and Expert Commentary

Attackers manipulate BGP by injecting fake AS_PATHs, exploiting unused ASNs to reroute traffic and obscure their identity. This technique bypasses traditional safeguards like RPKI, as stripped paths leave no trace for validation. The hijack involving Orange S.A. demonstrates how implausible AS relationships reveal malicious intent. Mitigation hinges on enforcing First AS checks, which validate that a peer's AS appears first in advertised paths. While most networks can implement this universally, exceptions exist for IX route servers requiring 'no enforce-first-as' settings. Vendors must prioritize secure defaults while accommodating legacy configurations to close this gap.

Action Items
