From 642f6b38169c5805676f061708d25137f4cc986e Mon Sep 17 00:00:00 2001 From: Nick Thomas Date: Thu, 22 Aug 2019 16:05:07 +0100 Subject: Send TODOs for comments on commits correctly At present, the TodoService uses the `:read_project` ability to decide whether a user can read a note on a commit. However, commits can have a visibility level that is more restricted than the project, so this is a security issue. This commit changes the code to use the `:read_commit` ability in this case instead, which ensures TODOs are only generated for commit notes if the users can see the commit. --- app/services/todo_service.rb | 6 +- .../unreleased/security-64711-fix-commit-todos.yml | 5 + spec/services/todo_service_spec.rb | 121 ++++++++++++++++++--- 3 files changed, 112 insertions(+), 20 deletions(-) create mode 100644 changelogs/unreleased/security-64711-fix-commit-todos.yml diff --git a/app/services/todo_service.rb b/app/services/todo_service.rb index 0ea230a44a1..b1256df35d6 100644 --- a/app/services/todo_service.rb +++ b/app/services/todo_service.rb @@ -314,11 +314,9 @@ class TodoService end def reject_users_without_access(users, parent, target) -
