Impact
A payments info page of Pay is susceptible to reflected Cross-site scripting. An attacker could create a working URL that renders a javascript link to a user on a Rails application that integrates Pay. This URL could be distributed via email to specifically target certain individuals. If the targeted application contains a functionality to submit user-generated content (such as comments) the attacker could even distribute the URL using that functionality.
Patches
This has been patched in version 6.3.2 and above.
Pay will now sanitize the
back
parameter and only permit relative paths.References
