Affected Functions

Version

rocket::local::LocalRequest::clone

<0.4.5, >=0.4.0

Description

The affected version of rocket contains a Clone trait implementation of LocalRequest that reuses the pointer to inner Request object. This causes data race in rare combinations of APIs if the original and the cloned objects are modified at the same time.
