Dancer2 0.206000 has been released, and it is recommended that all users of Dancer2 should upgrade as soon as it is feasible to address several potential security issues: - There is a potential RCE with regards to Storable. We have added session ID validation to the session engine so that session backends based on Storable can reject malformed session IDs that may lead to exploitation of the RCE. Please see the Storable documentation(https://perldoc.perl.org/Storable.html#SECURITY-WARNING) for more information. - We have changed from HTTP::Body to HTTP::Entity::Parser (the same as Plack uses) for parsing requests. Apart from being faster, this change also resolves a situation when forwarding requests where the request body could be re-parsed without correctly seeking a filehandle to the beginning of the request body, potentially resulting in an infinite loop. The implementation using `HTTP::Entity::Parser` does not require the request body to be re-parsed. This addresses a potential DoS attack vector. In addition to the security fixes, this release offers a number of bug fixes and documentation enhancements. Thanks to all who contributed, both old and new.
