Trigger.dev is a platform for building AI agent workflows with durable chat capabilities. A flaw in its snapshot-url API endpoint allows users to overwrite their own session's chat history, enabling them to forge conversations and mislead the AI agent about what was previously discussed. This affects versions 4.5.0 through 4.6.1.

## How to fix

- Fixed in 4.6.2

Restrict API access to trusted clients only or disable the snapshot-url endpoint until upgrading to the patched version.

## Technical details

The PUT /api/v1/sessions/:sessionId/snapshot-url endpoint lacks a secret-key-only authentication check that exists in its sibling endpoint. This allows public session tokens (issued to browser clients) to obtain presigned S3 write URLs and overwrite the durable chat snapshot. The vulnerability stems from missing authorization.type !== "PRIVATE" validation, enabling session token holders to forge agent message history in the durable storage layer.

## Affected products

- Trigger.dev Trigger.dev 4.5.0 to 4.6.1
