CyberRota Analysis
AI-GeneratedThe vulnerability in lib0 allows unauthenticated remote peers to exploit a missing bounds check in the binary decoder, enabling them to read adjacent process memory, which may include sensitive data such as document content and session tokens. This poses a significant risk for any application utilizing affected versions of lib0, particularly those that handle sensitive information and rely on socket communication. Organizations using these versions should prioritize immediate upgrades to versions 0.2.118 or 1.0.0-rc.33 to mitigate potential data exposure.

Original NVD Description
A missing bounds check in the binary decoder in lib0, versions 0.2.1-0.2.117 and earlier and 1.0.0-rc.32 and earlier, lets any unauthenticated remote peer read adjacent process memory and receive it back. `readUint8Array` never compares the wire-supplied length against the decoder's own view, so one over-long length prefix returns whatever the host process allocated next: other tenants' document content, personal data, and live bearer session tokens**, recovered in full and at will. An attacker who can supply bytes to a lib0 decoder which means any peer that can open a socket, including before authentication reads adjacent process memory and, where the consumer echoes, stores or re-serves the decoded value, receives it back. This is patched in version 0.2.118 and 1.0.0-rc.33.
