CVE-2026-127086

Description

Ryot before 10.5.6 contains an authorization bypass vulnerability that allows authenticated users to take over other users' collections by supplying an updateId to the createOrUpdateCollection GraphQL mutation. Attackers who know a collection id can trigger ownership reassignment without checks, read its items, rewrite metadata, and evict the original owner and collaborators.
