Summary
Rails has a possible XSS vulnerability in its Action Pack debug exceptions
Details

Impact

The debug exceptions page does not properly escape exception messages. A carefully crafted exception message could inject arbitrary HTML and JavaScript into the page, leading to XSS. This affects applications with detailed exception pages enabled (config.consider_all_requests_local = true), which is the default in development.

Releases

The fixed releases are available at the normal locations.
