The vulnerability resides within an unspecified component of Erlang/OTP. An attacker who successfully authenticates to a system running a vulnerable version of Erlang/OTP can potentially gain access to sensitive data that should otherwise be protected. The specifics of the vulnerability and its exploitation are not detailed, but the potential for unauthorized information access poses a significant risk to the confidentiality of affected systems.
