Descriptions
HTTP::Tiny before 0.083, a Perl core module since 5.13.9 and available standalone on CPAN, has an insecure default TLS configuration where users must opt in to verify certificates.
A vulnerability was found in Tiny, where a Perl core module and standalone CPAN package, does not verify TLS certificates by default. Users need to explicitly enable certificate verification with the verify_SSL=>1 flag to ensure secure HTTPS connections. This oversight can potentially expose applications to man-in-the-middle (MITM) attacks, where an attacker might intercept and manipulate data transmitted between the client and server.
