Assessment

An attacker with:

  • modify ticket-comments permissions

  • read tickets permissions

  • is assigned to a shared task (“Task_1”)

can edit and delete any task comment on that task (“Task_1”) as long as they are at least a “Stakeholder” on that task by sending:

  • A PUT /private/ticket-comments/{id} request, with the following payload:

    {"data": {"text": "<change comment to this text>"}}

    to change the text of that comment to “<change comment to this text>”.

  • A DELETE /private/ticket-comments/{id} to delete that task comment.

Expected:

Users should not be able to modify comments that they did not write.

Mitigation

Planned fix, where platform enforces permissions correctly.
