What is CVE-2020-35733?

An issue has been identified in Erlang/OTP prior to version 23.2.2, where the ssl application version 10.2 improperly accepts and trusts invalid X.509 certificate chains that lead to a trusted root Certification Authority. This vulnerability raises concerns about the integrity of SSL/TLS communications, as it could potentially allow malicious actors to exploit the flawed certificate verification process, compromising the confidentiality and authenticity of data transmitted over secure connections.
