What is CVE-2023-23589?

A logic error in the SafeSocks feature of the Tor software allows the usage of the insecure SOCKS4 protocol instead of the safer SOCKS4a protocol. This flaw can potentially expose users to privacy risks by enabling unsafe network connections, compromising the core purpose of the Tor network, which is to provide anonymity and security for users. Users should immediately update to the latest version to mitigate these risks.
