GoogleOSV:GHSA-3VFW-7RCP-3XGMactionpack Improper Input Validation vulnerability
EPSS
Percentile
87.5%
The to_s method in actionpack/lib/action_dispatch/middleware/remote_ip.rb in Ruby on Rails 3.0.5 does not validate the X-Forwarded-For header in requests from IP addresses on a Class C network, which might allow remote attackers to inject arbitrary text into log files or bypass intended address parsing via a crafted header.
