Description OSIDB Bzimport 2024-11-26 12:01:11 UTC 
In Nunjucks versions prior to version 3.2.4, it was 
possible to bypass the restrictions which are provided by the autoescape
 functionality. If there are two user-controlled parameters on the same 
line used in the views, it was possible to inject cross site scripting 
payloads using the backslash \ character.
