Token disclosure via plaintext proxy transmission
Published Jun 9, 2020 · Updated Aug 4, 2024
Information disclosure in Microsoft Visual Studio Code Live Share Extension allows remote attackers to capture plaintext tokens through a proxy. The client-to-proxy communication path transmits authentication tokens in plaintext instead of preserving their transport confidentiality. Exploitation requires specific proxy settings and successful interception of that path, exposing tokens without reported data alteration or service interruption.
