Dancer2 0.206000 addresses several potential security issues.
There is a potential RCE with regards to Storable. Dancer2 adds 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.
Parsing requests now uses HTTP::Entity::Parser which reduces the amount of code needed and does not require re-parsing the request body.
