From aaa7f0d92ee9c876c38da43be5c49e8d5c73a99b Mon Sep 17 00:00:00 2001 From: "W. Trevor King" Date: Thu, 13 Feb 2014 08:47:20 -0800 Subject: [PATCH] nmbug-status: Escape &, <, and > in HTML display data 'message-id' and 'from' now have sensitive characters escaped using xml.sax.saxutils.escape [1]. The 'subject' data was already being converted to a link into Gmane; I've escape()d that too, so it doesn't need to be handled ain the same block as 'message-id' and 'from'. This prevents broken HTML by if subjects etc. contain characters that would otherwise be interpreted as HTML markup.
