The following vulnerabilities have been discovered in rails, a ruby
based MVC frame work for web development.
A code injection vulnerability exists in the Active Storage that
could allow an attacker to execute code via image_processing
An XSS Vulnerability in Action Pack that could allow an attacker
to bypass CSP for non HTML like responses.
Action Pack is a framework for handling and responding to web
requests. Under certain circumstances response bodies will not be
closed. In the event a response is *not* notified of a
ActionDispatch::Executor will not know to reset thread local
state for the next request. This can lead to data being leaked to
A XSS Vulnerability in Action View tag helpers which would allow
an attacker to inject content if able to control input into
When serialized columns that use YAML (the default) are
deserialized, Rails uses YAML.unsafe_load to convert the YAML data
in to Ruby objects. If an attacker can manipulate data in the
database (via means like SQL injection), then it may be possible
for the attacker to escalate to an RCE.
For Debian 10 buster, these problems have been fixed in version
We recommend that you upgrade your rails packages.
