Security warning!
Using QUERYPARAMS can easily be misused for cross-site scripting unless specific characters are entity encoded. By default QUERYPARAMS encodes the characters '"<>% into HTML entities (same as encoding="safe") which is relatively safe. The safest is to use encoding="entity". When passing QUERYPARAMS inside another macro always use double quotes ("") combined with using QUERYPARAMS with encoding="quote". For maximum security against cross-site scripting you are advised to install the Foswiki:Extensions.SafeWikiPlugin.Related
