From 1c1819a78a33cb7a90b499676c587f3c6dd7406f Mon Sep 17 00:00:00 2001 From: Eugen Rochko Date: Fri, 7 Jul 2017 04:31:40 +0200 Subject: [PATCH] Fix feed author not being enforced in ProcessFeedService (#4092) Ensure the only allowed author of top-level entries in feed is the person the feed belongs to (a verified user). Ensure delete events only apply if the deleted item belonged to that user. --- app/services/process_feed_service.rb | 21 ++++----------------- 1 file changed, 4 insertions(+), 17 deletions(-) diff --git a/app/services/process_feed_service.rb b/app/services/process_feed_service.rb index fbdf92caa..028962d5b 100644 --- a/app/services/process_feed_service.rb +++ b/app/services/process_feed_service.rb @@ -42,7 +42,7 @@ class ProcessFeedService < BaseService private def create_status - if redis.exists("delete_upon_arrival:#{id}") + if redis.exists("delete_upon_arrival:#{@account.id}:#{id}") Rails.logger.debug "Delete for status #{id} was queued, ignoring" return end @@ -99,15 +99,13 @@ class ProcessFeedService < BaseService def delete_status Rails.logger.debug "Deleting remote status #{id}" - status = Status.find_by(uri: id) + status = Status.find_by(uri: id, account: @account) if status.nil? - redis.setex("delete_upon_arrival:#{id}", 6 * 3_600, id) + redis.setex("delete_upon_arrival:#{@account.id}:#{id}", 6 * 3_600, id) else RemoveStatusService.new.call(status) end - - nil end def skip_unsupported_type? @@ -128,18 +126,7 @@ class ProcessFeedService < BaseService return [status, false] unless status.nil? - # If status embeds an author, find that author - # If that author cannot be found, don't record the status (do not misattribute) - if account?(entry) - begin - account = author_from_xml(entry) - return [nil, false] if account.nil? - rescue Goldfinger::Error - return [nil, false] - end - else - account = @account - end + account = @account return [nil, false] if account.suspended?
