CVE-2026-114067: Trigger.dev 4.5.0 before 4.6.2 Improper Authorization via snapshot-url Session Route

Trigger.dev 4.5.0 before 4.6.2 contains an improper authorization vulnerability in the PUT snapshot-url session endpoint that allows public session token holders to obtain presigned S3 write URLs. End users can overwrite their own session's durable chat snapshot to forge the agent's conversation history, since the route lacks a secret-key-only check.
