Summary
CockroachDB PostgreSQL for IBM VPC contains a server-side request forgery flaw that lets a logged-in attacker send unauthorized requests from the system, which could be used to map the internal network or support further attacks. The attacker can reach it remotely over the network, but needs low-privilege login first.
