Ecosyste.ms: Advisories

An open API service providing security vulnerability metadata for many open source software ecosystems.

Security Advisories: MDE2OlNlY3VyaXR5QWR2aXNvcnlHSFNBLXF2MnYtbTU5Zi12NWZ3

Insecure randomness in socket.io

Affected versions of socket.io depend on Math.random() to create socket IDs, and therefore the IDs are predictable. With enough information on prior IDs, an attacker may be able to guess the socket ID and gain access to socket.io servers without authorization.

Recommendation

Update to v0.9.7 or later.
