What it is

Blinko through 1.8.8 contains an insecure direct object reference vulnerability in the tag tRPC router that allows authenticated users to read and modify other users' tags by supplying arbitrary tag IDs. Attackers can enumerate sequential IDs via fullTagNameById, updateTagIcon, and updateTagOrder to reveal private note topics and tamper with tag icons and ordering.
